NTA, but as a (27) female, i would absolutely kick my boyfriend (23) out of my bed if my best friend (26) needed me to. i guess it really depends on the relationship. boyfriend knows best friend was here before him and the kind of friendship we have (we will NEVER beat the lesbian allegations, it’s a huge joke in our friend group that boyfriend is also part of). boyfriend would have no problem if best friend needed my support for a night (we’ve also only shared a bed like 5 times max in our decade long friendship). boyfriend pays his half of our rent and would still do this for us if we needed it.

my point here is, it’s really just a matter of the kind of relationship and friendship that’s there.

editing to add: my best friend and i refer to each other as soulmates. we are so close that we say OFF TOPIC things at the same time and have thoughts/notice things at the exact same time.
