Please help me

Hey chat, I think my boyfriend of 12 months now is using me for my body every time we talk he turns it into something sexual and guilt trips me until I send him something and I can’t help it I love him so much and I send it to him but then he completely shuts me out and yk leaves me on seen or he would say smth dry and when I would try to continue the conversation he just doesn't put effort like I do. I know I sound like a fool but we have had our good times too, he’s the first ever person to make me feel loved in a way, I’m attached to him. He’s the only person that I have right now. Please help me.
