Friendship with the agreement of no feelings(but hidden) no commitment.

I have a very close friend of mine, "close" but we agreed not to go for commitment until I fall in love with him, I started to get jealous and and all my thoughts will always negative when i feel like he is lying to me. And he does. A lot of circumstances came out that i can prove he is lying to me but i can't confront him coz he is not my boyfriend. It happened and i was so open to him and all i want from him is to admit yet he didn't and he gave up on us. after he while he came back and i accepted him, we still the same close friend. No commitment and for sure on my side i knew he is playing around or he has somebody else.

We like each other a lot, for me i can't entertain someone else because i wanted to be available when my close friend need me. But if i need him he is not that available. I admit i am so silly but i don't wanna lose our friendship.

Should i stop seeing him and date someone?

Yes stop seeing him. Hes using you and your being a doormat. Its time to grow a pair and stop letting people walk all over you
