<human>: Can you condense the text into a few key points?

Hi, I'm aware this is long but I'm so lost, please help.

I have been with my boyfriend for around 3 months, he has been in 3 long term relationships where as I have always been single. At the beginning he was the most amazing, attentive person I'd ever met, we had only been dating for a few weeks before getting into a relationship. We spent a huge amount of time together because we had a lot of similar interests and I got on with all his friends.

Recently, I feel a bit like he has just lost interest in me. We occasionally go out for dinner, he takes hours to respond to my texts (I rarely text him, only when trying to finalise an arrangement). He claims to have been really busy lately over the weekends, which I believe, yet has made no effort to meet me during the week. He said that his past relationships have failed because his ex girlfriends were really needy, I'm very cautious about brining up the lack of communication between us as a result.

Long story short, I have had a few very messed up relationships, and my self esteem has hit rock bottom, I stayed single for a few years while I kind of rebuilt myself. My SO is the sweetest guy and most perfect gentlemen when we are together. I am very afraid that I like him a lot more than he likes me. I am also conscious that it is possible that I am reading way to into it and his excuses are genuine. But at the moment I am feeling so uncertain about our relationship, its all that occupies my thoughts. 

I guess most people would say talk to him about it, but our relationship is so new, I don't want him to think I am controlling, and there are aspects of my old relationships I don't want to share yet.
I'm not sure what exactly my question is... how do I communicate any of this without sounding insane? has he just lost interest in me and am I just the girl he has sex with occasionally? Or is he genuinely just busy and this kind of relationship is what he wants?

I'm sure I haven't been coherent, and I'm missing info but if you got this far please help x
<bot>: I'm in a new relationship, I think he's bored and going to dump me, I'm also cripplingly insecure so it might be in my head
