Met a chick over a dating app yesterday, everything's cool, she adds me on Facebook and shows interest when texting, instant replies etc. However turns out she has a LTR as her profile is riddled with lovey dovey photos with his bf. Asked her about it last night, she became evasive about it and I said I'm not looking to idly chit chat as I have plenty of friends for that, told her to introduce to her sister if she's hoping I'd be a third wheel. Anyway I said all this because I suspected she just wants to chat as she finds me a lot of fun to talk to but I also suspect that I couldn't handle the situation well enough and fucked up somehow. Any insight about this situation and how to proceed from here? I'd also like to add that if she's continuing the relationship I don't want to fuck this bitch as I'd hate to be part of a cuckfest of some hapless dude however beta he may be, that's why I wanted to clarify whether she had a bf or not.
