Should I give him a second chance?

[LindaSmiley]

So I posted a thread 2 days ago about my boyfriend who I've come to finally realize is very controlling.

He went through every email, facebook, phone.. I wasn't allowed to go out or drink at all. He doesn't like me having any contact with males even if they're my family! as I sleep with every man I meet & know. He was just overwhelming & just TOO much.

 

We talked about it all yesterday. He broke down told me about his past relationship were she cheated on him & broke his heart. He told me that he cares about so much & he just doesn't want to lose me. He said that I was really important to him & he just wants to make things work. He told me he loved me a million times. He didn't beg me to stay or act desperate. He wasn't at all angry or acted crazy like I thought he would. He apologized & completely understood where i was coming from. He even told me to change my passwords if I wanted & he told me he would respect my freedom.

 

I asked him if he wanted to come with me to a family get together this weekend & he accepted. My family & friends were all so surprised that I was going because I haven't gone to a family get together in so long. My best friend even told me that it was a big step because she knows how he is.

 

I'm just wondering if it's the right choice. Am I being gullible because I love him or should I truly believe him & give him a chance to prove himself?

 

I really want to believe him. Am I foolish for believing that he will change over night? should I give him the chance?
