Victim of Breadcrumbing

I have been with my boyfriend about 9 months, and he frequently makes plans and has to work through them. I have not met any of his family however he has met some of mine. He only messages when he feels the need...or desire. We have progressively moved from substantive discussions to purely superficial or sexual. I can finally see it. What I do I do now? I have deep feelings for this person, and just blocking him is difficult for me, especially since I am a people pleaser. Block with no closure? I'm completely confused, and my self esteem has been decimated. I feel stuck.
