Yo, tbh that sounds kinda selfish on her part. Like, relationships should be give and take, not just one person doing all the giving, ya know? If u feel like ur always sacrificing for her but she can’t be bothered when u need her… idk, maybe she’s not as invested? Doesn’t sound like u bein too sensitive, sounds like u noticing a real issue. U deserve someone who cares about ur needs too, man.
