I really need some advice!

So to give you guys some details- I'm 22 and my boyfriend is 27, we have been together 2 years in November, and we have a 2 month old son together. We have had our fair share of issues and honestly it's been a rocky relationship to say the least. From being accused of cheating to him job hopping and all around being sketchy for a while it's been frustrating.

On top of that I have a ton of debt now that we can't really afford to pay. And in case your wondering we weren't trying to have a baby but here we are.

My first issue is like I mentioned before he jobs hops but he told me he was gonna be better because we were having the baby. The thing is tho he hasn't been better. Our son is 2 months old and he hasn't worked a full week. He told me to stop working so i can stay home with our son so i did. (I know not my brightest idea but I had hoped he was gonna really try)

The last job he had was right down the road from our house paying really good and he called in the beginning of the second week. And he told me the reason why he did it was because I didn't motivate him to go to work. Why he wasn't motivated? Because we went to my cousins birthday get together the day before and had to stay longer for one of my other cousins to show up so he could meet our son and then one of my aunt's that couldn't make it asked us to stop by so she could meet our son as well. We went to my aunt's before we were gonna go to his aunt and uncles so he get stuff from there. He cancled on his family and then blamed me for making him do it even tho I told him we should still go and that there was plenty of time to visit. This isn't the first time he's blamed me for his choices but this one really gets to me. On top of him not working he barely does house work even tho he makes the biggest messes, he refuses to do yard work, and the only time he helps with our son is when I "bitch" at him about it. I've tried to talk to him about it but all I get is it's my fault and fights to the point that we almost break up.

My second issue is that when I say something about breakin up he threatens to take our son from me-among other things. Logically I know he'd have a hard time getting custody of our son. I own my home and have since before him and I got together and up until right before I had my son I had a steady job. He didnt get custody of his 5 year old because of the same things he's doing now but I don't know if I really want to risk it. And despite what i call our rough patch right now I do love him. I've never been one to just throw in the towel when things get hard but honestly this seems excessively hard.

Theres a ton of stuff i didnt get into but I guess I'm just looking for some advice from people not directly associated with the situation. Im not perfect by any means buy I feel like I deserve a little better than what im getting.
