Serious question! Need advice!

So this guy that I dated before wants to get back together. I agreed to try to date again like get to the point of it.

We have been hanging out and trying to be coupley again. Now it’s the summer and we only see each other once in a while. He thinks that when we broke up it wasn’t because we didn’t love each other and i agree but I don’t think I love him that way anymore because it’s been so long and we have been friends since then.

Nothing has changed and I still don’t really feel like I want to date him again. I’m afraid that I don’t like him more than a friend and I’m more just afraid to lose him because he was a very good boyfriend but I just don’t know if I feel it anymore.

Even sexual things I don’t feel like doing them with him. That’s also because I was never that attracted to him but I mean once we do it then it’s fine.

I’m also just worried I’m not giving it a good enough attempt because its only been a month and a little. He’s such a good guy and treats me right and loves me a lot and has done a lot to be with me.

I’m at such a loss of what to do and don’t wanna regret saying bye.
