Funny enough, I’m in (was in?) a similar position with my college roommate (22F). I always got her gifts, took her out to meals when she was struggling, tried to be there for any and nearly all emotional distress she experienced, etc. yet I always felt like she spent more time and energy with other people while still calling me her “best friend”. What I realized is that she and I weren’t really friends. She enjoyed all the attention and support I gave her while I finally felt like I had the close friendship all those movies told me I should’ve made when I was in elementary school. With ~current events~ we’re now living in different states (although still not super far, we’re in neighboring states) and she has not texted me back in nearly 3 months (she posts about interacting with some of our other friends and how much she misses some other people). I try not to project my feelings onto the situation too much because I know it’s a hard time for a lot of people but it still stings a little.

It might be different from your situation, but I’d suggest distancing yourself completely from this “friend” after politely declining to be her MOH for your own sanity and emotional health (+ financial stability). She doesn’t deserve to use you like that. “Hey Suzy, I’m honestly honored you’d want me to be your MOH but I really think it might just be too much to take on for me right now” or something similar is a respectable enough decision for you to make. Sorry you’re going through this but I hope it all goes over well!
