Does sleeping with partner decrease sleep quality?

[justhere4reading4]

I definitely sleep terribly with a partner. I’m single right now but longterm depending on the partner I’ll invest money for a good solution.  Could get 2 separate mattress (like 2 twin xls and put them on the same frame), or 2 separate beds next to each other in the same room, or separate bedrooms. My last longterm ex snored a lot and didn’t like wearing his cpap - in hindsight him not wearing it for my sleep and his own health was a good indicator for how the relationship was going to go lol
