My boyfriend (23M) has left me feeling drained and confused (24F).

Where do I go from here? To provide some context, I entered a relationship with my boyfriend after leaving a tumultuous nine-year marriage filled with physical and emotional abuse, which left me with three daughters and a lot of trauma. From the moment we met, he took on the role of a dad and partner as if it were second nature. He is the only father my youngest daughters have ever known. However, he's struggled with trust issues stemming from his own childhood and past relationships. I’ve always tried to be patient and supportive, but looking back, I realize I tolerated emotional abuse throughout our four years together. He often accuses me of cheating, especially in the beginning, where he fixated on my ex-husband. My ex would maliciously tell him that I was still in contact with him, trying to make my life as difficult as possible after our separation. After a physical altercation two years in, because he "knew" I had been unfaithful, I called the police out of fear for my safety. Following that incident, he went to anger management classes, and I thought things would improve. While he made some changes, I often felt like I was still starting from ground zero in terms of trust. He would watch my daughters while I worked, claiming he couldn't find a job, but he didn't help out much unless pushed to do so through conflict. After moving into a new home and starting my dream job, I took a stand about three months ago, insisting we wouldn't resume our relationship until real changes happened. He became paranoid again, particularly accused me of having an affair with a coworker. He has since acknowledged his mistakes and promised to improve, and while I've been careful to avoid arguments in front of the girls, he still makes side comments that concern me. Recently, he seemed to show progress by participating more in family activities. However, over the past month, there have been signs of regression—comments about my coworker and accusations of infidelity that make me uneasy. Despite acknowledging some of his past behaviors and their impact, he still believes my attitude is a major issue in our relationship. His recent behavior, including liking photos of other women while never acknowledging my posts, has planted seeds of doubt in my mind. I entered his social media and discovered he has been interacting with numerous women but not with me. When I brought it up, he blamed it on his suspicions about me and apologized. Today, though, he changed his passwords, and despite his initial apology, he seemed upset with me for being upset. He is the only father my children know, and I rely on him to watch them while I work; I wouldn’t qualify for much state assistance because of my income. I'm at a crossroads. It’s incredibly exhausting and disheartening. I know I deserve better treatment and that I'm unhappy, but I struggle with feelings of depression during breakups. I'm afraid of a leap of faith that might leave me homeless with children, especially since I moved 45 minutes away from my family to be nearer to his. Any advice would be greatly appreciated. I feel lost and alone in all of this without any friends or family to turn to. **EDIT:** To clarify, my first husband and I began seeing each other at 12 and started dating at 14, so it was more like 6 or 7 years, not 9.
