I have a relationship for 2years, but I know another beautiful girl.
I know that she wants to has sex with me but I don't know what to do.
She is beautiful and sometimes I think about how it would be with her but what should I do?

Not enough info - how much are you into your current lady?

Temptation is a huge thing. Is your current relationship winding down? Do you LOVE your current gal?

If you love her and want to sped the rest of your life with your current gal - don't do it. It will ruin your relationship.

I say - ifyou want to spend time with this new lady - break up with the current gal now. End it. Your mind will the be free to pursue the new woman. IF YOU can't break up - that's the test - you should not sleep with the new person.

I'm still in love with her but sometimes I think how it would be with the other girl and I just want to do it but I don't because I love my girlfriend.
Is this the right decission?

I think not sleeping with this other girl is definitely the right decision. Obviously there's something not completely right in your current relationship or you wouldn't even contemplate it but how would you feel if the table was turned and your girlfriend was thinking of sleeping with somebody else?? It's not nice and at the end of the day what goes around comes around!!

Well you don't want to cheat - believe me. Cheating sucks.

You did not make a decision.

If you want to be with the other girl - break up with your current gal.

Your relationship with your girlfriend will NEVER be the same if you cheat. OK?
