Bf keeps asking if I love him yet

He sounds insecure and clingy.

After ten years he has a different perspectve on his needs and this relationship. Yes, he is now in love. You, on the other hand, are still in the fwb mode. Be sure you are always honest with him about just how invested you are in all this. Not fair to lead him on.

I never allowed myself to think of him as more than fwb, mostly to prevent getting hurt because I didn't think he wanted anything more. My guard is coming down and I am developing feelings for him. I've been honest with him about this and would never intentionally lead him on. We were pretty close even when we were fwb. We went out and really were friends. He is very open an honest about what he wants with me and doesn't playing the dating games, which is refreshing. I get butterflies just thinking of him and the time I've spent with him. He has said things that make me think he has loved me for awhile, but I'm not sure if I'm reading too much into it. When He playfully said I was going to fall in love him and that it was okay, I said naw, you're going to love me. He then said well yeah, but you are going to be the first to say it. He is an amazing man and I am falling.

Then what is your problem? Enjoy this and stop playing a game if who is going to say it first. If you feel it, say it.
