So confused...have i lost the man i love?

So me and my boyfriend got into an argument about a month ago over something I thought was very pointless but I guess he got mad at me and we have been together for almost four years and been through EVERYTHING in our relationship…we have a son and have just recently started having a long distance relationship since I had to move back home but we have been trying to get on our feet so we can move in together but raising a baby alone is hard and I think he thought I was pressuring him or making him feel bad about not being here with us but I was just missing him and overwhelmed since this is my first child but we always seem to work things out after a fight because we are crazy about each other but I guess when we got into the argument I must have hurt his feelings (mine were hurt too but I got over it) but I have apologized many times through text, email, and voicemail and I had to actually call his mother (who doesn’t really like me that much) because I had tried for so long to get a hold of him to take care of a matter dealing with our baby but no answer so I really hope that didn’t make him more upset but at the same time I feel if we have a problem we should talk it out but he doesn’t really like expressing himself….anyways I miss him and love him and just want things to be back to normal and I know its because we are far away from each other….so do you think its over for good or he just needs some space?
