Am I with a child?

Sometime ago I posted about my boyfriend getting into problems because he went to play air soft with my brothers and they broke my sisters window broke and well I got really mad and kicked him out because he likes hanging out with my brothers friends who are still in high school and he’s a 27 year old “ADULT” and also because my mom and sister kept telling me stuff and I even had an officer at my door interrogating me… long story short when he left apparently he was mad enough to create online dating profiles in various applications and unfortunately I found out through my sister because she’s on them and he wouldn’t admit anything until I finally got access. He even swore it on his baby girl of 3 months! I’m really hurt as this isn’t the first time. He didn’t take any action in actually physically beating with someone I think but he did create another dating account when I forgave him for actions and took him back into my home. I asked if he did anything sketchy and he lied and kept lying to me until I uncovered the whole thing. Well im baffled on what to do… I really can’t handle my girls on my own without him especially right now that im about to go back to work. I don’t have a support system whatsoever on my side of the family since my mom has kidney disease end stage. Im hurt and im even more hurt I can’t leave him at the moment due to the situation. I really don’t want the relationship anymore because of many other situations and these last two invidentes really did it for me… Any thoughts on how I can possibly approach this? How I can try talking to him? I don’t want to talk to him. But I’d really appreciate feedback
