Love Crisis

I'm in love with my (guy) best friend. The only problem, I just got into a new relationship with someone else less 2 months ago. I've always been in love with him but I've suppressed it and lied to myself for 10 years out of fear of not wanting to risk the friendship and the amazing bond we have. My family practically adores my boyfriend already but I can't say they are as keen on my best friend. They trust him with my life of course but call him a job hopper because he's had more than 3 jobs(most of them he was forced to quit for varying reasons) since he moved out of state for college 4 years ago, they say he still has years of growing to do and are not fans of the choices he's made in his personal life. They say that they feel they have a good feeling that he is not a dependable person just based on their observations of him, they do not know him on a deep personal level like I do. My new boyfriend is great, sweet, fun, caring but he's stationed in a different state in the Army until March 2021. I find myself gravitating to talking to and play video games with my best friend but can't get myself interested in talking to or playing with my boyfriend anymore. My mom says I'm overthinking my relationship and that it will get better once he comes back to our state and it's just because I've never been in a long distance relationship until now, let alone started a relationship before I could even be around them in person. She doesn't know that I'm in love with my best friend and I know she won't react well if I tell her. I'm also polyamorous so she already doesn't agree(she doesn't hate it or me, just doesn't agree with it) with my love life choices as is. I live with her and she always finds out my personal stuff sooner than I'd like. I'm just really lost and could use some sort of direction. I've let myself get into such a rough situation and a deep hole and I do not know what to do.
