Update
She wanted to do something last Saturday but I had plans so said we would reschedule. I went on a Bumble date Friday after work which lead to sex, she called mid date and I said I was out having a drink with someone and would talk to her later. She knew it was a date and didn't contact me all weekend. I reached out on Monday over the phone as her texts were short, she said she was annoyed that I was still out meeting girls etc as we were both clear that we would, after all these year, put all our efforts into each other and see what would happen.
I responded saying she is still technically with her BF, potentially going on a 2 week holiday to the Dominican Republic in 2 weeks with him, so why should I put everything out there when she could turn around and say "I'm back with him" - she kind of went silent on that. Then said she doesn't think I will change and I will always want attention from multiple girls and maybe we should leave it, I said "fine, I'm not going to force you into anything" then she said she wants to have dinner with me at my families place soon...
So it feels like she's trying to lock me down as something stable to monkey branch to... but I'm not going to just wait around. My friend who knows us both agrees, he said keep spinning plates just don't let her know about it.
Anyway - we went for a drink after work yesterday, our friend last minute came along - she gets a call from her BF who now is unblocked on her phone. Basically proving me right. I've convinced her to have a BBQ this Saturday, she has asked me to come early to help set it up, then said to come over Friday and stay the night and that she wants me to make breakfast Sunday morning. She wants to come back with me to my place on Sunday.
I'm just going to see if I can smash this weekend but continue seeing and talking to girls, I am cautious until BF is fully out the picture.
