So recently I've felt like the beta orbiter in a friendship. Our texts have gotten shorter and we went from texting heart emojis everyday to texting 2 sentence blurbs all within 2 weeks. I don't know what I did wrong but I feel like I did. I want to cut her out since I'm guessing she's disinterested.

Note: Our history spans over 6 years of on and off talking. 2 weeks ago, we admitted we liked each other but then this happens. Again, she said she liked me since we were 16 but I think I effed it up. I asked her on a date as friends (she got out of a 3 year relationship and wasn't emotionally ready for another) and,she constantly blew me off.

I ask to hang out and she says she is busy (even though she hung out yesterday with coworkers and dinner). Our history has been me asking to hang out. Her saying yes, her cancelling and then saying she's too busy. This has been going on for about 2-3 weeks. My last text today was somewhere along the lines of "ok. I get it. I'll see you at 8:30 mass tomorrow" and she hasn't responded since.

I admit. I wanted to be passive aggressive although I may have gone too far. I'm tired of being the beta orbiter. I want to cut her out but I see her once a week. How do I not make it awkward seeing her tomorrow during service? Do I say hi and leave? Do I ask if she wants to talk after mass?

She sings so she can see the whole crowd. Its given we'll notice each other.

Edit: More stats, also, sprained wrist so lifting weights isn't an option.
