Don't know if I can do this anymore :(

I have been with this guy for a little over a year now and we have had a roller coaster of a relationship. He left his last relationship (he was with the woman for 10 years) when he met me and he went back and forth between us for the first 6 months of our relationship. I gave him one last chance and then I ended up pregnant and we have been together since then. We got a place together for us, his two daughters and my son and things were good at first and then took a nose dive. We had an argument when he was very intoxicated and I left causing him to go to his ex's and started trying to get back with her. The next day he came back and told me half of the story (the rest his ex found out) and we broke up for a few weeks but decided to try it again for our baby's sake. Since then we have been constantly fighting and I just don't know if I can trust him anymore. I love him and when we are good, I know this but when things get bad, I just don't know how they can get better. I want to make it work but I feel like we are at the end. Does trust ever come back? Do things get better or is it better just to call it quits?

Angel Eyes I am sorry you are going through this. Let me start off by saying that you did not cause him to go back with his ex. People get into arguments and even leave to calm themselves down it does not mean the guy can then go and cheat. So please do not blame yourself on that one. This relationship is young and encountering so many problems already it is best for you and overall the children for there to be a separation period. He needs to figure out what he truly wants and it is very important for you to know what you really want. After the separation if you both believe it is better together then great if not then you don't have to ride the roller-coaster anymore.
