Separation plz read all before commenting plz

well hubs told me he wants to separate he thinks he is in w his ex. (she has called me we have talked she never will happen so did my step son) he has done this before a matter of fact we been together 7 yrs and six months in he didn’t like he loved me so we broke up but bc we moved to fast when he asked to try again in a month i said yes. then three yrs in (married by then) he said he was in love with brother in laws cousins wife (her and i are very close they never even seen each other) he got mad when he found she was never going to leave her husband. then last yr he fell in love with some chick he met online (come find it was a scammer) now it’s his ex wife and it’s just bc he is over my step son moved back in with his mom and she let him take over the garage it’s huge three car so they have ben working in a demo over there and other cars.

now the thing is when this starts he still pays bills here he still lets me use his truck bc it better then my van. he starts to not shower (unless he is going over there) he stays either in camper or sleeper of his truck. he is always gone mon-fri and my weekends i work i do 16 hr sat and sun so he does whatever but he is still spending one weekend with me and my other weekend off i go stay with one of my kids or go to my sisters to help with our parents. i know i shld probably just say to hell and leave but i will wait it out and see what he does. he does this the same of yr between aug-nov normally last 6-8 weeks. my whole family just tells him whatever. i think it’s some sort of depression bc if isn’t breaking up w me during that time of yr it’s reckless spending it depression that has him taking personal days off work it’s funnfill trips that i love six flags any county fairs or he won’t even go to the races (first one he normally hates second one he normally lives and breathes racing). if u have read all this thank u and what do u think
