I need a serious advice from someone who is in a long commitment relationship.

Since I met my boyfriend I ve changed so much, I let all the fun part of my life behind me but I maybe sucrifised the immature part of me U gained the love of my life. We are living together almost since the day we spent our first night together.The issue is he texted a girl he tried to date before me one night, I saw it he explained he used to like her before me but he did it for his low self esteem... Because he has some issues I let it go. After I found some photos of his exs's on his computer he said he forgot about them and today I tried to find a link from yesterday on the PC and saw on browser history that he was checking other women photos on facebook. He said I do that randomly. After I said I want to break up but he cried and sweared on his life he wants to spend his life with me till we die.

I love him too much to break up.. I really want to be with him but I don't know if I am losing sight of what's right to do from being in love...Plus he is taking care of me like an angel.. How all that sounds to you?
