Search Results: i slept with him too soon

We’ve known each other for two years but haven’t spoken much till we got a chance to work together. The conversation started going really well - asked if I had a boyfriend and other personal questions. I told him I want to find a new accomodation and he said we could move in together. He texted me the same night to make sure I was serious. Then, went for a viewing but the place wasn’t nice. And then, I let him know I asked friends for help and if it doesn’t work out, I’ll start looking online. He said that’s good that both of us are searching. Then, I suggested we could hang out on our day off and he said yes. the next day, my friend was FaceTiming one guy I slept with last year and ‘my guy’ was with him at work. I only waved to say hi and that’s it. Then, ‘my guy’ messaged me if I was still coming over to his place for shisha and drinks with his friends and I confirmed and he gave me the full address. he also started sexual jokes like I want you baby, will we be eating each other, I will sort you out, stay over and we’ll go to work together the next day etc. I thought he was drunk so I was just joking but I put my standards - friends or something more serious. Next morning, he asked me to tell him what time I was coming because he had a training at his other job. He was running late and then made another sexual joke. I called to check if he left. He said he was very lazy and apologised twice. Then, I asked what happened that he suddenly started being sexual. He sweared he was just joking and he’s a serious guy. And if he had a chance, he’d come to see me. Then, I told him he can make it up to me. He said he’ll do very soon. I told him hopefully and I’ll let him take the initiative. He said ‘yes, I hope. Ok hun. You too’. Will he message me again or not? Do you think the other guy told him we hooked up that’s why he had a random conversation with me? Did I show him I’m a serious girl? Does he still want to move in with me?

After having a good time the day/night before, the happiness I feel is gone as soon as one bad thing happens, or even just when I go to sleep. I have no memories that bring me any sense of joy, even the good ones. My mum tells me that it's not normal, and I'm not really close enough to anyone to sort a larger variety of opinion (cut off social media and that to focus on studies).

I can say that I was happy when I look back on memories, but I feel nothing. Like I could've been on the floor in laughter after hearing a joke, and just none of that the next day. It only happens with the good mems too, which is an absolute pain in the ass.
Is this really not normal?

As a side note, I'm in the process of obtaining an autism diagnosis. If there is anybody on the spectrum that gets like this, please let me know! I really want to find out what's going on.

If you know what's up, please comment.
