Trying to be the girl he fell in love with

Most of my questions revolve around my fiance. I love him so much and I do not want to lose him again. I don’t know how to live without him. He broke up with me once before because he was scared and a year later he wants to be with me again. I went through so much pain because of him and now I am slowly trying to be the girl that he fell in love with…but it will take me a while. Since we love each other so much we are noramlly arguing over the dumbest things. Well he BEGGED me to come back to him and give him another chance but now I feel that he’s turning it around and to avoid an arguement he just won’t tell me what’s going on in his head. I’m afriad that I’m going to lose him and one of the worst things is that over the past week our relationship just doesn’t seem right and I hate it. Everything is switched between us. He’s less caring, he’s mean, and he can’t cum with me…and that was me with him and he was nice and did everything for me because he thought that I was going to leave him. Now I’m trying to be nice, I cum, and I’ll do just about anything that he wants me to because I don’t want to lose him. What should I do…and please don’t say leave him because I won’t do that. Please help me keep him…I need your help ASAP
