(26 M) (LTR 26 F)

LTR started as very submissive. Always doing the chasing. I was very aloof and didn't reciprocate much. I guess she didn't get enough comfort and now she took a step back. Less chasing. I don't text her much but when I do she goes on social media for me to notice that she is ignoring lol. Always snapping a bunch of people now. It's like she lowered me as a priority in her life. No one likes a needy girl I know but she's kinda like turning the tables on me. Doing me how I used to do her. She's been doing a lot of studying for finals so I haven't gotten laid in a week. Yesterday she asked me when I was free. I told her Friday (today) and Sunday. She said her friend bought tickets for a concert and can't do Friday. (She had told me this months ago). Sunday is Mother's Day so that's a no as well. She then asked me "what about during next week" I just said "idk we'll see". I wanna get laid. And I feel like the she's trying to gain power in this relationship. Do I go radio silent or does that come off as petty and butt hurt? When I ignore her for a while. She hits me with the "everything alright babe?" As I'm writing this she sends me a message via Snapchat telling me she wants to fuck me. If she wanted to fuck me she'd come over whenever. what's my best way to go about this. Is this getting disrespectful? Go fuck other girls ? Soft next?
