SO CONFUSED. PLEASE HELPPP.

So I've been talking to this guy for only 2 months. I'm 19 and he's 28 (yeah I know). I really am into him and he says he's into me also. He told me he has an job offer 8 hours away and he wants me to come with him. It's only been 2 months so I told him let's see where things go from there. 3 days ago my ex boyfriend(my first love) hit me up on IG. Me and my ex didn't end on bad terms. We never had issues. We were simply just happy and loving life. We ended because he wanted to focus more on his self(🙄) He didn't call it a break up he called it a "break" (wtf). I was really hurt because I've been with him from when I was 16-18. I was depressed and didn't leave my house for months. He eventually blocked me on IG after I tried to contact him since he wasn't replying to my text and I decided that we were over and it wasn't a "break". I truly love him and I'm not sure what to do. I also really like my new guy and I wouldn't want to back track to something that doesnt make me feel secure. I don't want to take him back if he's just going to leave me again. It's been a year since we've talked and talking to him again just feels unreal. Like a dream. I honestly thought we would never speak again. But here he comes right when I'm happy and doing good not giving 2 fucks about him till December 2nd. What do you guys think I should do? Go with the flow with my ex and explain to my new guy? Keep my new guy to see where things go?
