This may be long, so bear with me.
I began dating someone in early July and we met up about once a week or so. I had known them for several years prior to this. We started doing sexual things (not actual intercourse but other stuff) maybe 3ish weeks into the relationship. This was all fine: comfortable and consensual.
Then in early August he stayed over and we decided to have sex. We changed our minds and did 'other stuff' instead although he was quite persistent in trying to convince me to have sex. He stayed over (i.e. we slept in the same bed) and we both woke up at about 4am. I don't know whether we both naturally woke (e.g. in response to a noise outside or something). Regardless, he started moving his hand down into my underwear. I moved his hand away but didn't tell him no. He repeated this 3-4 times, with me moving his hand away each time, until I said "I'm tired" and we went to sleep. At the time I didn't think much of it, just that it was annoying/uncomfortable, but now when I think of it I feel sick to my stomach about the fact that I just went to sleep afterwards with him still there.
In early September, we went to a friend's party. We were both very drunk (him more than me) as were many others. When we went into the front room to lie down (friend had offered their front room for all those wanting to stay overnight as it was quite late, so there were matresses/futons set up) I was feeling very lightheaded and tired due to drink. He started to grope me a bit and then the whole thing happened again (hand moving into underwear several times, me moving it away but not saying no, etc.). I remember drunkenly asking him something like "Why do you keep doing that?". I don't remember what/if he answered. Eventually other friends came into the room and he left and I went to sleep. At the time I remember feeling very anxious and like I should leave the room and find my friends, but I was so tired that I was close to passing out.
I don't know how I feel about this all. I don't whether I'm just overreacting, or what I'm supposed to think.
