I have no idea what to do

I have been talking to a guy for about eight months, we talked about being serious many times, and our relationship really got serious. However half of our relationship was long distance, he travels for work so it just made our relationship really unpredictable, not knowing where he was going next, not knowing when we’d see each other. We literally live across the country, and met under the most random circumstances, neither of us expected to fall in love. And honestly it’s been really hard, and he’s been very back-and-forth, and he knows he has a hard time excepting his emotions and not knowing quite how to love somebody. We just went through a period of no communication, and we just FaceTimed for the first time in weeks last night and told each other how we literally can’t stop thinking about each other day in and day out. How we expected our connection to fade but it won’t. However he was the one who ended the communication, he ghosted me. So I started talking to my sons father again. And we talked about rebuilding our family and how we will always have love for eachother. However now that me and this guy have reconnected again, I really do feel like I am in love with him. And he told me last night he loves me. But I’m terrified to continue this relationship, because it is so unpredictable, and what if he leaves again, and I threw away the relationship I could’ve had with my sons father? Bc I do love my ex, but we were toxic. But we’re trying for fix it.. he was my high school sweetheart and 7 year relationship. But something about this guy… I know he is genuine. He just has so many emotional issues & traumas that hold him back from being emotionally available. but he is such a good guy at heart, and he’s trying to let his guard down.. I’m so confused.
