jumping too fast? what do yall think?

so first thing.. please dont judge me. i got into this relationship when I was 17. i was young, nieve, and looking for love..so here goes..my ex and I were together from December of 2015, until the 13th of this month. about 3 and a half years. I should've left after the 1st month but you know we get all caught up and think we think we can change someone. he killed my spirit, I was a dead drag just walking around depressed. he abused me. me messed me up mentally. he forced me to do things I didnt want to do and touched me places I didnt want to be touched and he thought just because he was my boyfriend it was "okay." he cheated on me countless amount of times and made me insecure by telling me how much weight I'd gained over the years. last month I went up state to visit some friends to get away from him, I stayed for a week. during that week I was introduced to one of their friends and it was almost instant chemistry. we all drank that first night and I was wearing a crop top and short shorts. mind you I'm 240lbs, I have rolls like crazy, and in front of everyone he called me "hot" and I didnt even know how to handle that cause I was always used to being called ugly and fat by my ex. I cried on his shoulder for an hour about how much I hated my boyfriend (at the time) and he gave me so much great advise. my other friend that was also drunk was crying her eyes out in the other room to our other friend about how she just wanted me to be happy, I thought it was so sweet and cute of her. we didnt talk much when I left until the day before I left my ex. the day I finally said enough is enough, I left my moms house and was on the way to my apartment and I caught him with a girl that I'd already caught him with 3 times in the last 2 weeks. I texted him and said "I'm done. I guess I'll go home and pack my shit since it's obvious who you want to be with." I'm so upset with myself that I stayed this long and let myself get so wrapped around him..I've been talking alot recently with the guy from upstate and I'm leaving tomorrow to go up and see them for my birthday on Tuesday. he gives me all these butterflies and constantly tells me how beautiful I am. my friends keep telling me to date him, but we haven't exactly talked about it. I mean..is it too early to date someone new? everything with my ex just happened not even a week ago. I dont know exactly what to do.
