Breadcrumbing

I need some advice. I don’t date at all really, and don’t have a lot of experience with guys. I chatted with this guy for about four months. He was nice and supportive. In the beginning he was really into me and gave lots of attention, however it has faded to maybe a couple of sentences a day. The idea of sex was brought up several times and he would want to come over( which I denied). I’d always ask him do you want me actually or do you want just the physical aspect? Fast forward to now and I met him last late last week. He was understanding of my anxiety and patient and it went okay. He told me I was pretty and that he’d like to see me again, however I feel like it’s still not as great as it was in the beginning. So my question is am I being breadcrumbed?? Any helpful advice?
