Search Results: flirting while dating

Cut a long story short I known this girl 5+ years and we always seem to flirt. But about 5 months ago I became single and I started spending time with her while she was with her boyfriend she use to ask me how she should break up with him etc. Anyway we started going to dinner and going to the theatre etc. So there I'm 3 years older. When we go out she 9/10 comes back to my house where we watch t. v. and chat normally on my bed and she like it when I played with her hair. So about 3 months ago she became single. Then she seemed like she didn't want to know me we had a conversation and she said she had so much work on so I let that go, so we went out and it felt like it use to the flirting etc i asked her about dating and i she said atm she's not looking or wanting to be in a relationship so i said okay but if it because u dont wanna be with me just say so and she said no its not that i asked her if she had any feelings for me and she said she doesn't wanna tell me so it's comming up her birthday and some of you would say stupid of me but I got use a weekend away. I booked this a month before her birthday. Now I told her a few weeks ago and she said it was good and she is looking fw to it. Then she's gone a bit of the radar. Then my friend has see her pop up on tinder. So I feel like i been betrayed but I shouldn't as I'm on tinder to but she known if she said let's date I would drop tinder like no tomorrow. Our weekend away is comming up in a few weeks.

What should I do?
Is she playing games.
