Idk what to do . Sorry for long post .

My bd and I have been together for 2 years and share 8 month old twin girls , we live together , I’m a sahm and he works two jobs to support us . For context , these pst two years we’ve been broke , got evicted from the last two places , our car got towed last summer , and we’ve been making ends meet since then we moved in with mom for four months , then moved again with some friends and their daughter and then finally he saved up enough to get us our own place and his assistant manager at both jobs . The girls and I are currently out of state visiting family for what was supposed to be 2 weeks now we won’t be going back for another 2 weeks . Before he left , my bd never took a day off , he just worked all the time , since we’ve been gone he’s taken days off , gotten off early , gone home on his lunches , he barely communicates with me , he never answers his phone and only seems to call when it’s convenient for him and then still keeps the call short . I don’t have a location for him , he’ll get upset and tell me I’m starting drama for questioning him and not trusting him . Girl , I don’t trust him . I believe he’s 100% cheating or talking to someone else . He’s been a completely different person since we’ve been gone and hasn’t expressed any feelings towards missing us or wanting us home . He doesn’t tell me he loves me .he’s super secretive about his phone , he has my location , my phone password , I communicate my whereabouts and plans and nothing is reciprocated and he’ll still have the audacity to tell me “you better not have anyone around my kids “ or “idc what you do” does whatever it he wants without repercussions or consequences and still scrutinizes me . No dates , flowers occasionally, I don’t ask him for money , he’ll usually give me money for diapers and stuff for babies when needed but I don’t ask him for anything outside of that . I cook , clean have food ready and his work clothes washed for him , the babies are fed , clothed , bathed , cared for . I make every holiday , birthday for him special even if I don’t have shit , he fought with me on Mother’s Day . He swears I’m the problematic one . I cater to his every need , I’ve had his back through everything all the good and bad , went through the struggle , carried our twins so we could have the family we always wanted . All for what , so I could get blamed for every problem we have , all for someone new to reap the benefits ? He thinks the grass is greener on the other side but hasn’t even taken the time to see that his grass would be green too if he watered it .
