OK so I was with my ex for 3 very happy years. Everyone thought we were made for each other we got on so so well then he broke up with me pretty suddenly and I couldn't understand y, I eventually found out he had been having an affair with a married woman we both worked with, I was completely devastated he was the last person on this earth I would ever expected to hurt or betray me in such a way. I then left that job and went somewhere else. 4 months later he got intouch with me via email I didn't respond for a few days. As much as he'd hurt me I couldn't stop thinking about him or stop loving the person I thought he was. So eventually I replied and we met. We talked and then he held me in his arms I felt safe again and as if everything was going to be OK. We decided we'd give things another go, I explained how much he had hurt me and hed have to understand id have major trust issues now but I was willing to give it ago. He thot it would be best to keep it secret for a while as he thot my parents and family and friends would give me a hard time. 2 weeks after getting back togther he went to a party. All I asked was for him to text when he got home safe. The next morning I still didn't have a text so I waited until evening time as I didn't want to seem like a nag. When I still hadn't heard anything I called him he said we would chat the following day. So the following day I called he said he didn't think things wer going to work out between us that I could do better and hed never be good enough for me. Then the next day I found out via Facebook that he was ''in a relationshio'' I was gutted he had done it again. I was comppletley destroyed, couldn't eat or sleep. I lost about 3 stone and was so lost. 4 weeks later he text me to tell me he was engaged and getting married on 12th August 2011. I haven't heard from him since I've seen him once in the town we live in but I was in the car and he was on foot. When I saw him I instantly missed him. Some days I hate him but other days I miss him so much and long just to talk to him, he was my best friend and I miss him. Should I try to make contact?

HELL NO!

You are going to some how have to see this guy for what he is... a cheater, liar and a user.
PLease go no contact( read the stickies at the top of the relationship page). Why would you even consider contacting a person who treated you this way... not just once but twice! Forget about him and find a guy deserving of your love.

Thanks for your comment deep down I know your completely right in what you say sometimes I just need it pointed out to me!

He is engaged and he has not treated you well, twice.
Leave this clown alone and move on.
