Hello. 

First of all I would like to say i feel blessed because I found this site. 

I'm stuck in a pretty bad situation.

A little background. I have 2 sons, ODS 19 and YDS 15. I got pregnant when I was 17 (youth mistakes and bad choices...) and my ODS' father left the scene before his birth. I married another man (YDS' father) but 6 years ago we saw things were not working out anymore, so I left.

4 years ago I met my now husband and we married 3 years ago. He has 2 daughters, OSD 17 and YSD 15. From day 1 they never accepted me. OSD is very standoffish towards me. Always were. Never tried to know me. We don't talk to each other and I'm disengaged from her.
She's not bad or mean, but honestly, I won't persue a person who is clearly unwilling to have anything to do with me. YSD was always a b*tch. Never liked me, never warmed me, always made clear I mean nothing to her, Me and my family are not family to her.
Once, actually the first time they were seeing my mom, my mom said she was happy because she always wanted to have a GD, YSD told her she was not her GD, me marrying her dad doesn't make me or my appendage her family, etc. My mom was sad, hurt and shocked.

My husband always corrected her, always punished her for her bad behavior, always parented her. Didn't change anything. I decided to disengage from her to. It takes two to tango, she clearly prefers another dance.

BM is an obsessive woman and never accpeted me. His family never liked her.

My MIL loves me, says I'm a good woman. 

My sons like my husband, they are happy I'm happy. Their dad found another woman, which is making him pretty happy. I'm honsetly happy for him, he was never a bad husband, but love came to and end for us.

His daughters never liked my sons, never tried to know them, always excluded them. YSD last year made a false allegation that my OSD was harrassing her.

Yesterday I was holding a lunch at our house when we heard someone knocing furiously at our door. It was BM.

My MIL opened the door and BM screamed: "I'M HERE TO TAKE MY DAUGHTERS AWAY FROM THAT HOUSE!"

My MIL started to fight with saying she wouldn't take anybody and claiming she would call police.

"YOU BETTER DO THAT. BUT FIRST, TAKE A LOOK AT THIS, YOU OLD WH*RE"

She gave my MIL a smartphone, my MIL started to see what she was showing and then exclamed "oh my God! DH take a look at that"

My DH took the phone, seconds later he said: "Is that ODS? F*ck! I'm going to kill him!"

I asked him what was happening he said: "YOUR SON! YOUR SON IS HARRASSING MY DAUGHTER!"

I told: "Can't you see, BM is poisining you with lies. False allegations again? Change your tricks, honey"

Well, I unleashed the beast! She was angry and told me: "LIES, LIES, YOU WH*RE? TAKE A LOOK AT THIS, MOTHER***KER"

I took the phone and I almost puked when I saw the screen

It was a video of my son masturbating he sent to YSD. 

"READ EVERYTHING, YOU WH*RE!"

I read. Dozens of messages with sexual content, dozens of photos of him naked, a video of him peeking her on bathroom. It has been happening for 6 months.

I couldn't believe. I almost fainted. I couldn't believe my own son would do this. 

"SO, WHAT ABOUT THE LIES NOW, YOU WH*RE? LET ME SEE, IT WAS CLEARLY ME DRESSED LIKE YOUR SON RUBBING MY SH*FT TO MY DAUGHTER, ISN'T IT? NO!!! IT WAS YOUR MOTHERF***KING PEDOPHILE SON, A GROWN MAN HARRASSING A TEENAGER!"

When I heard those words I couldn't hold my tears anymore. I could believe. I fought so hard to be with the man I love and my son destroyed everything. BM now has full force against us.

She said: "I'M TAKING MY DAUGHTERS WITH ME RIGHT NOW!"

My MIL said: "Take them, it is the best thing to do"

When they were about to leave, BM told my husband: "You will never see those girls again!"

He sat on sofa, clearly shocked. He was speechless.

My MIL sat next to him, when he said: "I will lose my daugthers. It is all my fault, I falied to protect them"

My said: "Actually, it's your wife's fault. She is the mom of that disgusting pedophile. She was the one who made my gd look like a liar. She clearly knew what her son did that time. She made us believe my gd was lying to protect her son."

It's not true. But i had no forces to defend myself.

He left about an hour later and went to his mother house. Haven't talked with me since. 

I was there alone, my sons were at thei'r dad's house.

That image of my own son doing that disguting act repeated in a infinite looping.

I'm sad, I will probably lose my husband. I'm feeling like a terrible mom, how could a rise a son like this? I'm felling like the worst human being, what if that false allegation wasn't false at all? I'm afraid for my son's future. BM will obviously after him. He will go to jail.

I'm not here to seek validation for my son's acts. What he did was terrible. No woman deserves to be harrassed, never. The fact my YSD never liked me and excluded me won't change my mindset. 

I came here to try to unburden.
