My ex.

My ex (f19) and I (m19) broke up a little over 2 months ago, we were no contact for the first month but eventually started talking again, we hung out and we got along well. Next day her mom invited me out to a bar with them (yes,underage) and me and my ex ended up being flirty and when we got back to her place we hooked up. Since then we hang out a lot, sometimes days on end at her place. We do couple-ly things a lot (cuddle, hold hands, sex, cook & clean together etc) our breakup was rough and was mostly my fault. I get mixed signals a lot from her. Just looking for some input and other opinions on if there’s still something between us?
