Should i stop talking to him?

theres this boy I really like and I've liked him since august 2008 he used to like me and we was seeing each other but I dint feel the same way until I came back from holiday, we also had a row and we used to be like sorta good friends I saw him down...

the city last week and been talking since then really, like how we used to bestfriends any my question.

he has a girlfriend, we talk a lot on msn he flirts with me, he came round the other night to see me as we havent spoke proberbly in ages well I love him.
but I find it wrong him flirting with me on computer when he has a girlfriend 2 of my friends think same as me one of my friends said so. but I like him a lot.
and he's the one who always start the conversations.

should I just stop talking to him? because I really dont want to what should I do? because I've only just got him back as a real good friend again after like a year. ? ://

I think the same thing as your other ffriend. I say so? your not doing anything wrong. if he always starts the conversations then you just do what you use to before. he oviously still has feelings for you and you might too.

yeah I have feelings for him and always, but im not to sure he do :/ there's no telling with him he always make flirty jokes.
