What are my limits with this boy??? Can we even be the close friends that we want to be, with no problems??

Question

Theres this boy named daniel i met him about 4 months ago, i saw him all the time, and we would just smile and say hi, i had a little crush on him, and we would flirt a little. Then about 2 months ago I met a new friend named Leah. Leah and I aren't really close, but were cool. So I found out a month ago that daniel and leah go together, which was a surprise to me. Now I dont like daniel anymore, were all just friends.
Daniel and I have been talking a lot lately, about everything, even his relationship with leah. Were starting to be really good friends, even so much to where he invites me over his house, but only to kick it though, nothing else. I do know that i cant go over there without leah being there, so although we plan this stuff i don't plan on following through on it.
I just want to know what are my limits as to how close of friends we can be??? Were like getting to be best friends, and nothing more, but i don't want leah to question our relationship and think otherwise.

Were Even going to church together with my family on sunday. Leahs his first girlfriend, and he would just ask me is it normal for him to feel a certain way, and stuff like that.
I feel like just by talking to him so often im betraying her, Am I?
Should I tell him we can't be friends?
I'm kind of confused.

I also catch him comparing the Leah and I sometimes, see im more of a girl who likes sports and video games, so alot of times we talk about that. And he'll say something like leah doesnt like when I play video games, and I said if i were your girlfriend i probably wouldnt either but since im your friend im cool with it.
I jus wan to know what I should do, my conscious is really on me.

Answer 1

You set the limits, thats the problem, because your asking us for them. Its on you, your ethics, your morality, and your purpose. Technically yes he is cheating emotionally on his girlfriend leah with you, image how much better their relationship would be if he spend all that efforts on leah and not you. On top of that, this looks like a classic relationship were the males just in it, tell he finds better, he found better and now he's hoping that you'll jump on the wagon so he can dump old leah out of the picture. Look at it this way, the only thing there doing, that you guys are NOT doing, is having sex. That and the occational, "I love you". So this is set up to breck leahs heart, if you will it, on you....
