What Would You Do if You Were Me?

My fiance and I have been together for almost 4 years. We have been living together almost 3 1/2 years. We have a 2 year old son together. I love my fiance, but its one of those relationships that when its good its great, and when its bad its awful. I am a stay at home mom and he thinks because i dont bring home the paycheck that i dont work. for example today the house was clean, except for the dishes (which there isnt that many) because i went to the dmv for him and that took up some time and he freaked out called me a slob and that im lazy i musta been sitting on my *** all day. i got mad and yelled back that i do work, i dont get brakes, i dont get days off, i dont get a paycheck. i get $20 a week to pay for diapers, wipes, dog food, soap, shampoo, etc. im on food stamps but the rest of his check goes into junk cars he thinks he can fix up and sell for more money but we've made nothing or a video game or whatever else he wants. He then broke 3 christmas presents which were glass that i already had wrapped and spent time making them (they are collage picture frames with some of my sons pictures for my mom and his dad) and left. i tried to call him, no answer, i texted him to just come home and eventhough we were mad, that we could work through this. he texted me back to f*ck off. i tried to text him to call and say goodnight to our son but no answer. this kind of stuff happens all the time. we are good for a few days then fighting again. I have thought of leaving him but I really dont want to and everyone says i should because its in the best interest of my son. which i kno that my son doesnt need to be around us arguing i get that and im not staying with him just to be a family im with him because i love him despite our faults. i dont kno how much more of this i can go through though. im not sitting here saying im perfect so dont get that idea. i just dont kno wat to do. ive suggested relationship counsiling and he said no. he doesnt believe in counselers. half of me is saying that i love him and wanna be with him and we'll get over all this eventually, but the other half is saying that maybe its for the best if we go our separate ways no matter how much i dont want to lose him i cant be selfish.

the best thing to do would be relationship counseling. if he refuses to do that then he obviously doesnt want to fix the issues that are going on, threaten him that youre going to leave him and see what he says. if he fights for you tell him you want the counseling if he doesnt fight to keep you then leave his sorry ***, youll find someone who cant treat you much better and will be a more positive role model for your son.
