how do I know which path to take?

So I am having some relationship issues now and I feel like I am essentially making a choice between two guys who are in love with me, or say they are in love with me. I started dating a guy I worked with, Ill call him J., about a month before I left to go to Germany for an internship for three months. We decided to do long distance until I got back and we had a crazy connection, always laughing together. I regret doing this but I got on tinder while I was there just hoping to find a friend so I wasnt so alone. After about a month, I ended up cheating emotionally and physically consistently until I broke up with J. I started spending a large amount of my time with S. who 1) knew I had a boyfriend 2) was talking to other girls but still told me he loved me before I broke up with J. I didnt realize how it would affect J., he had been cheated on before in his only other official relationship and is a recovering alcoholic and narcotic and relapsed after everything happened. When I got back, I reached out to him and we still have a lot of emotions there but I am now in an official relationship with S. who wants me to live with him and get married in a state across the country once he gets out of the military. S has been married before. And I also ended up sleeping with J after I got back. Essentially both men are in love with me and both mean a lot to me and I dont know what to do. Especially since I have betrayed both of them which is a whole separate issue.
