What can I do about my extremely emotional cat whose need of love seems to outweigh what I can realistically give him?

I feel like every time I turn around I am asking a ridiculous question about my cat. But here is what happens. I have been extremely stressed out lately due to work, and also some personal/health issues. When I get off work and want to escape these issues (last night for example) I head over to my boyfriends house. Last night, I was only dropping his bike off for him at his house, but I was so tired that I crashed in his bed. I got home just now to my cat SCREAMING as if he was being murdered. It was to the point where I almost started crying because I literally could not handle this insane cat on top of everything else going on in my life. When nights like this happen (I’d say on average I spend 2–3 nights/week at bf’s house), my cat will hold a huge grudge against me for hours after I do get home…he wants nothing to do with me, he’ll run from me when I try to pet him, hide, meanwhile the whole time screaming like a banshee. It is blood curdling, and terrible, and frustrating, and why does he do it!!!!!!!!!!? So for example yesterday, I was not gone the whole day. I slept in til about noon, then was around my house doing various things, keeping him company, all day! I left at 5 PM and came home this morning at 9 AM. He is extremely upset.

Ever since I moved into an apartment where it is just me, no roommates, and the cat, he seems unhappy and like he is not satisfied with me. This is extremely upsetting to me as I love him so dearly, he is such a goofy fat weird personable cat. But this personality trait of his, I am having a really hard time with it. Today I think I almost reached a breaking point that I previously didn’t even know existed.

What the hell do I do about this cat who is so damn needy that I cannot satisfy him!?!!?!?!?!??!?! I don’t know! I have had him for two and a half years and all signs point to “He Hates Every Other Living Thing” Aka getting a second cat, not really an option. At this point though I am considering it anyhow, maybe he needs company?

OMG somebody please help before I go INSANE. Has anyone ever had a pet like this before?!?!!??

If it helps he is 10 years old.
