I broke up with him after almost 4 years if I was wrong...(Plz take the time to read or Plz dont answer) Thnx.?

We started off as friends, then we started seeing each other. He was the first guy who had ever made me feel special. As time progressed he moved in with me, lost his job & his car got repo'd cuz he couldnt make pymnts. So for almost 2 yrs, I ended up supporting my son (10), myself & him. Then I had found him with dating accounts & talking to other women asking if they "had a man". He said he'd never do it again. So I pay some tickets for him(I didnt want to see him go to jail), hired an attorney & pd restitution n reinstatement fees. Then Im lending him my cars cuz he finally got work, I asked him to please go to work n back, he decides to drink & drive, go places after work, & gets caught driving on a suspnd lic, again. Ok then he loses his job again, n starts talking to women on the phone I bought n service I was paying for, I let it slide. He said he would never do it again, again? Then his family flies him to where they live for 3 weeks which I have no problem with, he hasnt seen his daughter cuz his x just left state without telling anyone. Within those 3 weeks were "fathers day, (which really bummed my son out), My 30th birthday, his birthday, & 4th of july. I talked to him maybe 6 times in 3 weeks. he didnt even call to say I love u. (I checked in with him daily when I was in OR to tell him I missed him) On my Facebook page on my bday he decides to "like a female "friend" who was in a bikini & it shows up on my page" that hurt. Then he is an hour late posting "happy bday" my friends said it first. Then his bday rolls around n I try to call him to personally tell him, n "his family wouldnt let him answer the phone" cuz they were at the bar. I was the 1st on FB to say it though. So then, he comes back 1 day b4 our anniversary n he goes to the store knowing my son is hungry, buys food and eats it in front of him, So i told him to leave , he apologized & told me it was wrong to eat in front of my son.. Hell yeah it was wrong ,since I was providing his meals for almost 2 years without help.. He starting to get really negative So I told him he needs to move out until he has a job. So the last words out of his mouth were, "Im gonna try this time baby for us, 4 real." We dont talk for almost 2 weeks and then I find out he is in the hospital from a head injury, for talking to another dudes chic at a bar.. That hurt bad, I really thought he was trying. Then I take him back,(I love him ya know) but he's living with his brother & now I see him 8 times a month if that, thats hard for me considering he has been with me every day for almost 4 years. N lately he doesnt contact me & now since he started another job, he's too busy to talk to me, even after he is home, he ignores my calls & texts, but says he loves me when he does see me. Which I was stood up this weekend so, 6 days a month, oh n hes not spending xmas or new years with me so I get to see him literally the first week of next year... I told him it was over tonight and it hurts soooo bad..he tricked me, Am I seeing this situation correctly did I do wut was right? Is there any reason I shouldnt move forward? I am so Lost now..Not to mention my dad died 2 1/2 weeks from today a few years ago n I really struggle at xmas..Please give me some hope..Thanks
