still in love with the EX

So my ex  and I broke up about a year and half ago . He is in the army and I am in our home state. Him n I are really close because he is best friends with my brother in law. We dated and it didn't work because of the distance . I am in school so I couldn't leave to live where he's stationed. I was hurt and I cried but I got over it out of site out of mind. Well basically I thought I got over it until he came back for my nephew his gods sons birthday . He moved on gotten married and with a baby less than a year . :( . That should have been me but circumstances were at stake. So I seen him and all the feelings and everything came rushing back . We started to rekindle what we had before and he told me he didn't want to lose me again .i feel the same way . I've known him ever since I was 15 and I still love him .... any suggestions on what I should do ???
