me and my cat

Well, I moved out nine months ago. Prior to that we lived together for about 3 years....Our relationship has been on the rocks since. He always thinks I have one foot out the door and I'm about to run any second of any day. (Which is sorta true?) I hate being told what to do, and he's bossy by nature. We have a tendency to get on each others nerves and argue about things that are really, really stupid. We have two cats, one came with me and one came with him. They are buds. HIs is 17 and mine is 10. HIs has health problems and mine is, somewhat overweight. I have left my cat with him over the last 9 months with the intention of some day taking him to my place, but I can't quite muster up the heartache to take him away from his buddy...
Meanwhile, my roommate at my apartment came back from overseas and had to quarantine, so... long story short, I've been quarantined with him for days on end. We argue. NO resolution. I'm ready to run and take my cat. this is it. thanks covid. no end in sight..
