helppp!! Should I get over my ex?

I had a great relationship that ended a few months ago. it was about 9 months long. the guy broke up with me, and we stopped talking for a couple weeks but then became good friends again. since the break up he’s dated two other girls, one of which I feel like he had a crush on her while we were together. but anyways, they were both really short relationships and apparently didnt mean much to him..and I also dated another guy (that only lasted a few weeks) even though I feel like I wasnt over my ex. But lately I was feeling like I had finally gotten over him after all of this time. his girlfriend then breaks up with him and he calls me as a friend because he is upset. and now he tells me how much of a connection we had. and that he still loves me and wants to be with me again. he says that nobody can compare to me..and well it really hurts because I was just getting over it all. and now he’s coming back into my life other than our friendship. to make matters worse, at the same time that he confessed he still loves me I had just met a new guy that I like. but I dont know him that well and I do still love my ex. (my ex didnt know that there was another guy until after he told me he wants me back) so anyway. should I keep talking with the new boy or think about returning to my ex?
