You are obviously a more tolerant person than me.  I would never have agreed to a step moving in if I lived in a 1 bedroom apartment, no matter for how short the duration.   I would have said to DH, you can give them money for a hotel, but they are NOT coming here! 

I've been in a similar situation and feel you sister. It's ridiculous to feel unwelcome in your own home that you pay for.  When adult children move home they fall into the old role of parent/child dynamic. DH sounds like a disney daddee and ss is more than happy to take a break from adulting.  Hopefully he really does move out shortly but he sounds awfully comfortable.  

Yikes. 

This would be my nightmare situation and one that I worried about when skids started getting to the late teens...because DH seemed to have this fantasy that they would want to come live with us...or need to come live with us...after they turned 18. He brought it up with all skids (except YSD...he'd given up the dream by then).

Any time he brought it up I was completely noncommittal...but willing to die on that hill if it ever came close to being a reality. No. WAY. 

When YSD turned 18, he turned the basement room into additional office and studio space for himself (which he needed) rather than fixing it up as a suite "in case one of the kids ever needs a place ot live" as he's been thinking and dreaming about for years. Hallelujah!! I don't know what prompted him to let go of that idea, but I'm so glad he did. 

Of course, he can't push the darlings out completely...so he did get an air mattress "in case one of the kids ever needs to stay over." Now several friends have used it...my niece and nephews...my brother...but never skids. They always stay with BM even though DH always offers and we have way more space (BM lives in a 2-bedroom apartment...) 

Oh well. Baby steps...and I don't mind if skids stay over at all. Just if they live there and wouldn't leave...that would be an absolute nightmare.

OP, make a back-up plan for if SS refuses to leave and DH refuses to evict him.

I certainly hope you have a plan for what will happen on the 23rd if the freeloader is still in your home.  I think you should discuss that plan with your husband well in advance of the 23rd so that he understands just how serious you are about it.

Put some fish in his pillow, play classical music, and get flirty down and dirty with your husband.Your place is too comfy for him- I wrote a repsonse to your other post and feel for you,but you have learned from this.

Hope he's gone soon, and you never let him back in!

when I had SKids living with us I would stand at the door, key in hand and not want to go in.  It is a horrible feeling.

you need to get him out. Just do it. If DH objects, tell him he can leave too.  He is way too selfish not to see this situation.

I’m going through a really hard time with my 21SD. I hide in my room when I’m home and I know it’s affecting my own children (12, 10). I’m sorry you are dealing with this too. 

Same here. My SS21 is at mine and DH's house more than he is at his place of residence. Sleeping on our couch and just mooching everthing we buy. DH refuses to tell him that he can't spend the night even though he does not live with us and has his own room where he lives. He still lays up in my house days at a time without leaving. I go straight to my bedroom when I get home and he is there. DH doesn't understand why it bothers me so much for SS to be there.

Time to drop a bug in the land lord's ear and take the Skid's presence off of the table.

One of my SS visits from another town without notice. Imagine my joy when I arrive home from work and he is reclining on the couch with food in one hand and teasing/razzing up the dog with the other. I feel like going back to work.

Oh my, I remember your pain! DH and SS didn't have a clue why it would bother me. I'd work all day, come home to SS in my living room watching ESPN after getting up about 3:00. I'd then be trying to figure out what to cook for the 3 of us for dinner, going back to the store or stopping on the way home, etc. SS had a depression issue and he quit meds and dropped out of college. It took almost 2 years of doing absolutely nothing before DH told him it was time to get a job or go back to school or something. He did and seems to be back on track even though he quit meds again. I hold my breath and pray he doesn't relapse and want to move back in because DH sees no reason it should bother me that much to have him there. It's hard to say anything as well since it's a mental issue, and what if he tried to harm himself?

I too would look for something to do before going home! And my day off if DH wasn't off was always awkward too and I didn't want to stay home and watch tv or work on something there if SS was hanging around. He never had anything to say to me either because he never did anything or kept up with current affairs or anything to chat about. ugh just so hard, sorry!!!!!

I feel ya, sister. I endured an omni-present SS for an entire summer and then for an entire month of winter break. Couldn't find a summer job good enough for him and bio Mom lives in a boarding house with several other women, so we were stuck with him, 24/7, for a total of 5 months that year. I nearly lost my mind, and DH nearly lost his wife.

You have my absolute sympathy, and my absolute encouragement to get up on your hind legs and throw the bum (or bums if it comes to that) out.

Minimizing the size of your home is one way to mitigate this problem.  Since you have already done that and you still have a Klingon of a SKid problem, start moving in large furniture that you pick up on the side of the road or buy from GoodWill for cheap.  Once you squeeze out the Klingon you can donate the big stuff back to GoodWill and take the write off.

Make your new furniture collection "hobby" have an end game in mind.  The end game being to purge the adult Skid from your home.

Good luck.
