i’ve been dating a guy for about 4 months now and he’s been so good to me, given me absolutely no reason to worry about anything and always reassures me when i need but i can’t seem to stop convincing myself that he’s getting sick of me or that he’s just using me like even if his tone changes slightly or he doesn’t message me as much sometimes it makes me overthink everything and i start worrying that he’s gonna get sick of me and leave me and honestly it’s ruining my mental health and i don’t know how to stop it?? does anyone else experience this or know how to deal with it?
