I have two baby daddies

At the time... I had recently been dumped by my now ex fiancé. He was my first dream come true, the fairytale shit. We were happy, so I thought, and then out of no where he left me. It was devastating to me, I had just began to look at wedding places and dresses. Mind you I'm 18 years old, just graduated high school. I moved back home and left far from him, I didn't want to stay in Texas anymore I had nothing holding me there so the big Apple sweet home it was. So I came got a part time job while I finished high-school. During all that, I let lose. I gave no fucks about any relationship anymore. My dream was crushed. My ex, first love, still in love, came back into the picture. We had sex ofcourse. And we stayed at it for months. But it slowed down, he was busy with marine training. So I had another option of hanging out with my other ex. We had sex the one time we met up. From all that I only gained a pregnancy. Right now I'm stuck with a 6 months belly and two possible dads. One is a phsyco, that I've grown to learn, the other is in another state doing marine stuff. Both are supportive, I'm in love, secretly, with one. I wouldn't want a phsyco around my baby and I don't want a false relationship with the marine. I am taking a dna test soon but I'm Hella scared who'd it be. Any advise please. Or someone who's dealing with dna testing.
