I'm so full of resentment and anger that I'm ready to end it.  A little background... I am 49 and have 3 grown children 26,28,30. I have been with my husband almost 7yrs. He has 2 girls..8 and 12. Their bio mom has only been in their lives for the last couple years. So I was the one who potty trained..taught to shower, tie shoes, read, etc etc. My husband had to work out of town alot. At first it was only suppose to be a week. Then a week turned into months, then a year. I made it clear that I didn't want to raise anymore children. But somehow I have become the only parent. I have talked to my husband many times and expressed how he was putting me in positions idid not want to be in and I was becoming resentful about it. He would try and be better for a day or too then right back to non existent.  For example...since girls were 4and 8..he would just pick girls up from daycare drop them off at home and leave...all night. Then as girls got a little older...he feels it perfectly fine to leave them for like 12 to 24 hours straight. I feel that's wrong. So I'm stuck again taking care of his responsibilities. Don't know what to do!!!
