Help??

me and my boyfriend have been together for 3 months as of yesterday. him and his friend went on a little road trip to AZ for a week but before that he decided he didn’t want to go to college or atleast for right now because he just doesn’t have an interest. i told him to do whatever he wants and i would most definitely support him in whatever he decides. anyways he skipped his exams for the classes he was taking because for the last month before his trip he didn’t even go to class. everyone has been asking him what he’s going to do with his life and he doesn’t really know what he wants to do but he does need to find a better job because he works at a movie theater right now and he’s been stressing out since he left for his trip. since he left and came back i’ve noticed he’s been distant and won’t really talk to me about what’s bothering him and won’t let me in and that’s been causing me to be kind of a bitch and lately we’ve been kinda of arguing (that never happens for us) and we have been active but he said he hasn’t really been in the mood the past few days. i just recently got my license and a car but my car isn’t fixed yet. he thinks we’re both stressed about our own problems and someone said to give each other space but that’s hard because he lives 45 minutes away and my family is out of town for a week and he didn’t want me staying home by myself for that long so he picked me up and i’ll be with him until my family comes home but i can’t leave because again, my car isn’t fixed. sorry this is super long but does anyone have advice or tips that i can use to help him out both mentally and in the bedroom
