Embarrassed and disappointed

So my boyfriend was at work and I made his favorite dinner and even put on my very first thong because I wanted to have a really good night. Well he tells me that he’s going to go out with his friends whenever he told me he didn’t want to go out tonight so that’s why I made what he liked, I said okay and still continued with me night. He got home at 10:30 and I can’t tell if he got High or drank some because he acts the same way with both of them and so I’m laying on the bed with my thong and after I had my baby I’m a little on the chubby side but not too bad and he just looks at me and says I’m going to bed, gets his night clothes on and just gets under the covers and rolls over. No I love you or goodnight or anything. So I feel embarrassed for being in this thing while I’m big and I don’t even get told how I look in it or anything. I’m just so upset and I tried to get him to cuddle me and he keeps saying to leave him alone 😫💔
