Cheating partner

Obviously confront her, let your feelings/anger be heard and then cut her out of your life.

Confront her.

There is nothing worse than a guy who jumps to conclusions and makes decisions with a hot head.

Whilst you are 99% sure, 1% still indicates that you may be wrong. Even if you are not, you deserve an explanation from her.

If you don't mind me asking - how did you find out?

She was away from work, so I've been using skype to call her. I couldn't get on my skype because i forgot my password, anyway she gave me her password so i could use hers to ring her. Anyway I left it logged in by accident and this morning a notification popped up to someone she was working with abroad.

I think these sent sms's are conclusive enough ...

--- Hello sexy...are you asleep?
----By the way my UK mobile is +*****. Thinking about you xx
----where have you gone?
---ok I'm back xxx

Is there an evidence in the skype past messages of her responding to those messages in a similar manner?

I have guy friends who are very friendly like but they are gay! If anyone read the messages from them, they would think I am was cheating on my boyfriend but I'm not - its just the way our friendship is.

I can see your point though. I still think you should confront her about it. If nothing more, after 2 years you deserve a decent explanation.

Yes, I see what you're saying but those are messages she sent.
