Ok, where to start? I have been with my boyfriend now for 4years. I am in love with him, but recently I can't answer why I am.
He's in the Army, but just before he went in we had split for a few month then sorted things and were back on track, however I had a gut feeling he had cheated, so became paranoid and a total mess. Turned out I wasn't crazy. But because this happened before he went in the Army I forgave him, figured the Army changed him. For a while it did!

Not so long ago I found out he did it again, he had sex with one of the girls twice, there were 5 in total, one or two were while we separated, however he felt the need to lie about this.

Stupidly, I know, I have chosen to let him prove he's sorry. I can't forgive him at the moment, and everything in me is saying 'GET OUT!' but I really love him and feel that he can change.

But on my quest to find out if he had cheated I checked his Facebook. My heart went out of my mouth! He had arranged with my best friend of 10 yrs (I'm only 20) to meet her, told her he liked, however they both deny anything ever happened, and I've lost her, also, he tried with my sister :O

Arrrrrrrrrrrrrrrggggggggh! My heads a total mess, if anyone has any helpful advice I would really appreciate it, the obvious leave him isn't necessarily what I want at the moment, so anything else?

Lemme tell you something. I may be just 17 years old, but you need to listen. Some people never change. It's best to move on even though you love him. It will be hard to, but everyone's strong on the inside, they just need to believe that. Everyone has the power to change anything. Your guy will never change. He might, but he will go back to cheating on you. Why am I so sure? Well, if you don't tell him anything that he did wrong, he will go back to cheating on you. If you don't let him go and move on, he will go back on cheating on you. Like I said though, he might change his ways, but he really seems like the kind of guy that won't. Just move on, and if you can't seem to let him go after the relationships officially over, see another guy, or hook up with one :)

Leaving may not be what you want, but its most definitely what you should do. I mean being lied to, and cheated on for so long is just a preview of what you get from this fellow.

You can do better, move on, and chalk it up to youthful inexperience with dealing with reality. It's a growing pain, and will teach you a valuable lesson, if you run now before you are ruined further.

His behaviour, is unacceptable, you putting up with his behaviour, which shows by the fact that you're still with him, is just as unacceptable. You might as well be telling him to go out and have fun cheating by staying with him and forgiving him so easily. By now, and by that I mean 5 girls later, he knows you're not going anywhere, so what makes him think that 7, 8 maybe 10 girls you're going to go anywhere either. Put your foot down, you can do so much better than this idiot.
