Need help!!!

So the past couple of days when my fiancé touches me I'm sorta like disgusted...I still love him and there is times when I don't feel like this so I know it's not that I'm not attracted to him. I have been with him for 6 and half years and this has never happened. Like certain times when he tries to touch me I cringe or like move away. It's so weird cuz it's not like me at all 😞 also last night I went out I had a little stomach ache so I wasn't going to drink but I decided oh one won't hurt  cuz my stomach ache went a way a little and drank one. We left about 330 and got home at 6am I went to the bathroom and threw up I feel a little better now but I feel like I was hit by a bus. I can usually drink 3-4 and be totally fine so I don't really understand why I couldn't hold down one ...another thing I ate at 7pm last night and this morning at 6am I threw up what I had eaten at 7pm and I'm pretty sure it shoulda digested within 11hrs and that I woulda had dry heaves.
