My coworker is obsessed with me

I (28m) have a coworker (27f) who is is obsessed with me, we both have to go into office 2x weekly and the whole time she just wants to sit in conference room with me. When we work remotely it just transitions to teams but working from home I can make more excuses of xyz and why I can’t speak which I can’t do in office. We both work in adjacent teams, I’m the swe and she’s in a pm kinda role.

Selfishly she’s been a great benefit to me in terms of my job, since she’s the pm anything I do big or small will be reported to my manager on her projects standup call something along the lines of “he did something no one else can do” “he’s a genius” it can be any task big or small it’s always told in a manner of something like I’m always the hero. This has been going on for 6 months now and she regularly makes plans to meet outside of work which I always decline due to random excuses, also sends me texts after work hours about some inside jokes we have or it can pictures of her doing random stuff. I know she likes me but I’m not interested in her romantically. Although I do love our friendship and we’ve gotten to be really close these past few months which I don’t want to lose. Not sure how this will end up playing out but anyone have any kind of advice ?

I’ve tried a lot of things, like replying super late to her, sending one word replies, rejecting plans after work etc. I don’t want to lose our friendship but also don’t want to lead her on.
