boyfriends mom (18M) mom made him break up with me (18F)

i, F18 have been dating 18M for around 3
months, we’ve known each other since the beginning of the year. i learned his mom is super strict and over-bearing, but didn’t think anything of it, she was super nice to me when we met the first few times, then she got more overbearing when she realized this was pretty serious. i won’t lie, we have snuck around to hang out, but haven’t done anything bad. around a month ago she wouldn’t let us hang out anymore one on one, had to be with his whole family or not at all. so, we would go to the gym together without her knowing, etc. today, he said he was at work when in reality he was at my house. (his parents cut his phone line off so he has no tracking) when we got back to my house after doing whatever around town, his phone suddenly connected and his location started being shared. his mom immediately calls with threats and he rushed home. i get a call around 830 and it’s him ending it with me due to his mom threatening to kick him out unless he cuts ties with me. he now has no phone, no connection to the outside world, and can’t move out as he has no stable income
and is enlisting in the military soon. i really need help, this is my first serious relationship and im just distraught now. i know he didn’t want to break up and the last thing we said was i love you but how am i supposed to know he’ll come back to me?
