Just need some advice.

Summer

So I got invited out by a dear friend of mine who happens to be male. We’ve been great friends for a couple years. Nothing behind it. Now my SO wasn’t feeling well, as we both got invited to go, so I asked him if it was okay if I went cause I knew he was sick. He took NyQuil just 10-15 minutes ago and said he was gonna pass out, and to go out and have fun. I get shaded just about instantly after I ask. He gets quiet to me, and I continue to ask if he’s gonna be mad if I go without him and he says “you do you.” I continue to ask if he wants me to stay home, I’ll be happy to just let me know. He keeps saying go. So I went. The entire time I was out he makes me feel like shit about leaving him, so he walks to the store to get drinks (alcohol), which is fine with me. He just continues on making me feel bad for leaving. Now while there I wasn’t doing anything wrong, I danced by myself, sang karaoke, and took a couple shots. I literally just got home, walked into the room, and INSTANTLY get ignored when I spoke to him. I feel like I’ve done something wrong when I haven’t really done anything. Have I? I don’t see it as a problem to go out with friends and have a little fun as long as I’m respectable, which I was. He hates going out, big crowds aren’t really for him. Which I understand. Now does anyone think I’ve disrespected him in any way? I feel like he’s just doing this to manipulate me and make me feel like shit for having a little fun. I dunno. I just need some advice. Cause at this point I’m in tears and I don’t know what to do or even how to handle it anymore. 😞
