Can anyone help me figure out what I need to do?

[Beth]

So I've been dateing this guy for 2years. He works for my brother which makes things difficult because complaining about his boss is complaining about my brother. I actually met him through my brother.We started off with an AWESOME relationship. He ended up spending our first new years with his family and called @ 11:30pm to tell me he was with them and that he was about to come see me, I was mad that he hadnt called before then so I didnt answer and the next morning I broke up with him in a text message. A week later I called him to tell him I made a mistake and that I wanted him back. We started dateing again, it got VERY serious and I ended up moving into his apartment. After a while I had so many complaints and we ended up having lots of problems. Most of them I kept to myself. I had finally had enough so I called it off and moved out. About 4 months later I found out that he had asked my other brother (shortly before i moved in with him) about marrying me. At that point I started to go over everything we had gone through and realized that when problems came up I ran from them. And I realized that I never told him how I was feeling and that things bothered me. I wrote a long letter to him explaining everything and a month later we got back together and decided to take it slow but It went serious again very quick. I found out that he had lied to me about some things. Nothing major but with my past relationships minor always seemed to turn into major.Every serious relationship ive had ended up in me being lied to and cheated on. I broke up with him on dec. 1st and I hadn't talked to him in a month till he wrote me a letter telling me that he loved me and that he always will. Ive seen him twice now and I feel like I want to be with him again. He has his issues, has made his mistakes and can be a little childish but is very good guy. He always tells me how beautiful I am and that I'm the best thing to happen to him. What do I do?!? PLEASE HELP!!!!
