What is it?

There is this one guy I have been friends with benefits with him for one year now, and I don't really know what to do now. I don't really have like strong feelings for him, but I kinda like him but I have my doubts.

Why? Doubt him when you don't have strong feelings about him, when the relationship you have with him is good enough?
Well since I have been busy with him, I haven't really felt like going on dates with other people because some part of me has the feeling I am kinda dating him. And that I don't need anybody else and just him, eventhough we are not together it kinda felt like cheating if I did it with someone else when he is in the same city. But I had no trouble being with someone else when he was in a different country. Well at least that was so when we just started.
But how longer we are together how harder it became for me to be with someone else. Now this month has been the first time in a long time that I have slept with someone else then this guy, and it felt kinda strange at first. Because I feel like there is some kind of connection between us but I am not sure yet what.

What my problem is I am afraid to ask him what he wants out of this. When we are together it feels like we are sort of a couple, we can talk about everything and we cuddle and give kisses. So that feels right and good to me, that is what I really like about him, but than the fact that he has a son who is almost an adult and our age different is quitte big if I say might say so. Also I feel like he has already done everything he wanted to do in his life and I am still exploring mine and see, what I can do. With him I have the feeling he is okay, with how everything is going. Not having to explain where he will be or who is going with, not having to go on dates all the time. Just when he wants to hit me up and we choose a date and I come by, sometimes we eat something together and than do the thing where we came for and than talk inbetween it. And that just feels right.

So what am I suppose to do? Should I just leave it how it is and try to date in te meanwhile or just see how this will go with him?

One part of me wants to be with him because he helped me with alot of things and everything feels just right with him. Also I don't feel like he fullfills me but just adds something good in my life. But the other part of me thinks it is not good to be with him. Only because his way of having a relationship and the person he is, is so different of what I would like it to be. And it might be good for me, but I would think go crazy about him. Eventhough I know I can trust him and all that but it just a part of me that I really don't like. The jelaous girl I can be is so annoying and is not a part of me I don't want to have and don't want to be. Not a lot of people know this, but I can hide this part really good, so only the people who truly know me have knowledge of this part of me.

But for now I will leave it for how it is, because I don't know what I want too. Also I don't want tor ruin everything I have with him now. Cause I don't want to go searching for someone els to share everything with now. As soon as I find someone or he finds someone else will see what happens than, but for sure at the moment we are good for what we have.
