<human>: Could you distill the essence of the text into 1-3 sentences?

I met this guy around new years and we really hit it off. We spend a lot of time together and things are usually great. Recently, however, he's been having a lot of mental trouble. He is 23, usually unemployed, has a kid and a bad relationship with the child's mother. Also, he had previously cheated on me with her (which I forgave and took him back for). Anyways, I'm young, just moved out and I'm starting my career but he is so stuck in the past, living with his grandma, no interest in bettering himself or making a life for us. I really care about and love him, and I've been trying to work things out but he's just not having it. And now he's accusing me of sleeping with his friends and a bunch of other completely ridiculous things. Also, I'm not super attractive and have terrible self-esteem and a fear of dying alone which isn't helping. So am I wasting my time? Should I try to move on? Help :/
<bot>: BF cheated, I forgave him, took him back, he went crazy, we broke up, mixed feelings about taking him back or not.
