This whole story is raising a bunch of red flags for me. How are your relationship issues going to end up impacting other outside partners. The other people who you are going to be getting involved with are also full, human people with needs and feelings as well. One night stands with a DADT are probably fine. If you are looking at anything ongoing though feelings have a way of developing and if you don't have all your shit together in established relationships the shit can hit the fan in an epic way. Figure out how to communicate openly and honestly with each other before adding more people. (Your more people will appreciate it).
Everything will be ok in the end. If it's not ok it's not the end.
