Should I stay with my girlfriend?

I’ve been with the same girl for three years and two years now and we’ve just takin our first “brake” last week. This past Saturday I went to a party and met this new girl and it was obvious that we had a strong connection. My current girl and I have absoutely nothing in common but we still get along great and I love being with her but this new girl I met have many things in common and she’s realy easy to get along with and talk to. Should I stay with my girlfriend or should I get with the other girl?
