Welcome to the collective. Do you mean right for you as in “plan a life together” or right for you as in dating?
If the latter, a guy is right for you if you enjoy being with him, if you have fun together, and if you have some common interests.
If we are talking life partner, you need add in that the two of you have worked to know each other well, you share common values, you respect each other, you want the other person to be happy and successful, and he makes you feel that he wants that for you.
As to what to do about having feelings for two guys, don’t date either one exclusively. Date them both. After some time, your feelings should clarify.
