I know this might be a bit long but please read.Thanks in advance for any replies, need some advice, because I dond really have anyone to talk to about this.I met my boyfriend last summer on holidays.He was working there, so we stayed in contact and when he came home in October we met up again but didn't start going out until december. Things were going well until my birthday this year in june. We went on holiday together and one of the nights he got drunk and hit me. He said hewas so sorry and that he'd never hit a girl before and was ashamed of himself and that it would never happen again and hasn't since and I forgave him.but last week I was a bit suspicious, I know his password for his emails and I checked them. I know I was wrong for doing that but I'm glad I did. I found hundreds of emails from girls he was with while he was working abroad last summer, he had stayed in contact with them the whole time we've been together. in the emails he kept talkn about meeting up with them again and how much he missed them and wanted to kiss them and f*** them again.I I was in complete shock.Hes been emailng these girls every day but he just sais it was flirting and he was never going to see any of them again. But I went back to april in his emails and realized he'd been texting and emailing a girl here organising dates and stuff he said it was a one night stand and he was sorry but I rang the girl and she said they had met up 3 or 4 times and I found out he'd cheated on me with another girl back in jan/feb.Im gutted. e said he didn't realize how much he loved me until may and he wasn't with anyone since but he still emailed the other girls hemet while he was abroad nearly every day. when I confronted him he said he was so sorry and begged me to forgive him. wats making this work is that I've just moved in with him and I have a a 3 year old daughter from a previous relationship that gets on extremely well with him and sees him as her daddy.he's done everything he can to try and make this up to me but I don't know if I can ever trust him again knowing he has never been faithful to me while we have been together. Is it possible for me to forgive him for this and for him to change? he proposed to me yesterday and I don't know what to say, id appreciate any advice thanks
