Is it normal to end the friendship i have with a guy?

I was in your shoes recently as well so I hope I can help.
I met this guy while working this past summer and we became fast friends. However at one point, i noticed deeper feelings forming between us. I tried to ignore it because he had a girlfriend but no matter how hard I pushed my feelings down, one look at him and all sense was gone. We eventually gave into our feelings and spent the night together. The next morning i was expecting him to hate me or be ridden with guilt, but instead he started acting coupley. He would hold my hand and kiss me when we were alone. I didn't know what to think at that point. I didn't see him for a few days later but when i did i sat him down and talked to him. I asked him what this meant for us. If he wanted to be with me now. I wish i could say he immediately chose me, but that wasn't the case. At first he couldn't make a decision. And that hurt more than anything else. That i wasn't his obvious choice. but i told him i would wait. i would give him till the end of the week, and if he didn't give me an answer by then, I would walk out of his life for good, for both our sakes. That Saturday he gave me a ring and told me he's willing to do what it takes to be with me.
Now it wasn't easy for us, there were a lot of problems that we had to overcome, and still are working on, but at the end of the day, i love him. And I am so glad i didn't give up on him. Being with him, makes me the happiest girl alive.
So thats my story. Honestly i can't tell you to stop seeing your guy, because that would just make me a hypocrite. And i can't tell you to stay with him either when i don't know your whole story. At the end of the day you're the only one who knows what's best for you. But what i can tell you, is to ask yourself these questions before making a decision.
1. Is he worth it? The pain, the heartache, the stress, is it worth enduring to be with him?
2. Is he special? is he unlike any other guy you've ever met, or is he a dime a dozen?
3. Does the good outweigh the bad? If there are more bad memories than good, than thats how it will be throughout your relationship.
4. Can you forgive him? this is crucial, because if you feel like you could never forgive him for not choosing you first, than that will come back to haunt your relationship.
Anyways, thats really all i can do for you. I hope i helped even in the slightest. Best of luck dear.

Are you male or female?

Think of yourself first and foremost. He will never change so move on babes.Sad as it is, that is what you should do.

Yes.
