Why it is so hard to get a decent guy around here?

well im 18 and I been with this guy for 3 years and we have a baby girl together…every since the baby ame we alway argue about the stupidest thing. Then one day he hit me so I called the police…everysince then we havent talk much…but a week ago he been coming everyday to visit her and alway tell me sweet thing and said he still love me and wanna work things out…bt all of sudden one day he just said no we’re not gonna have a future together and leave…I was really sad but then a meet this one guy…he really sweet and nice…he know I have a kid and was a little uncomfortable but he still accept it and said that he like me a lots…so yesterday we went to hang out and got really really close…almost to the point of sex but we decided not to…I was really happy but then this mornin he text me said he sorry he have a girlfriend…he said when he meet me he was sad cause he and his girl is takin a break but he really like me but the only problem is my lil girl…then he said he wishes that he meet me before my boyfriend so he can bring me a better life…well now im confuse I really like him bt I guess if he truly wanna be with me he would love my lil girl too…so I dunno I dun need a man but sometime its just nice to have someone to talk to.
