sexual attraction issues, lost in love

So long story short, I was with my previous partner for 3 years. We started dating at 17, I am now 21. We broke up last year but are still immensely close. Our relationship isn’t like others, he is my bestfriend and my main support system. I will forever love him, and I mean really love.

We see each other every second day, hang out and cuddle occasionally and now and then we peck each other on the lips. Now the thing is, when I do all of this stuff I do it because I REALLY love him. But I know for a fact I am not IN love with him, nor am I sexually attracted to him. I think if I was sexually attracted to him, then I would be in love with him-because in reality there is nothing else stopping me, I love him to bits.

We always talked about getting married, and I have always seen a future with him married , and as the father of my kids etc. And I thought I could get over this sexual attraction stuff, or perhaps let it slide considering I love him in every other way….But can I really?

Help a girl out here. Opinions welcome!
