All I can say is you need to fix this problem ASAP. My husbands 19 year old daughter decided to start acting out about a 1- 3 months after we got married and it has literally ruinined everything. Our entire first year of marriage has sucked bc of her. I keep telling myself I cant just walk out bc of her and divorce was never even an option, but lately I cant stop thinking about how much happier I could be and less stressed and dont deserve to deal with all the drama. In your case he is young and impressionable and you can probably stop his behavior before it is too late...but you have to make sure your boyfriend is on board. My husband is a psychiatrist and internist and has a solution to freakin everything, but the girl just wont listen to any of it or get help. The 3 year old is probably just acting out because he is either angry or rebelling. Maybe he is pissed that you and your child moved in, maybe he is jealous or does have ***** mom issues? 3 is proably to young for counseling but you or you AND the boyfriend should see a counselor in behavior therapy so you can correct the sons behavior at a young age. Also, you dont want his behavior rubbing off on your 22 month old or putting your child in any danger or an unhealthy environment. Just fix it now bc the problem will never get better and honestly if my step daughters mental health and drug problems were there when I first met her father, I never would have gotten involved. This **** never ends and she isnt my daughter so theres not much I can do. I am too young and I feel like all my youth has been sucked out of me! Its so tolling on our marriage and I can honestly say I hate her too. She is too old for me to put into a time out but believe me ive had conversations in my head where I give her a piece of my mind lol. I dont like talking to friends or family about any of this bc 1) they have their own problems and 2) dont want them to know all the details and 3) just say things like, you knew he had kids when you got involved etc etc

Anyways, sorry for rambling but I understand your position and why you hate him. The resentment will eventually eat you up if you dont open up about it. You have to say something to your boyfriend in a calm, reassuring non aggressive way. Sit down with him and talk calmly. Offer suggestions for solutions and compromises. Hope this helped a little
