I feel like I was leaning this way and I feel she wouldn’t be keen to hang out if she wasn’t interested but feels strange in some ways as we haven’t added each other on socials (not sure if that’s even weird at this point).IMO if you've been on half a dozen dates and are keen to pursue it further, I'd do that.
Talk to the girl you've been seeing about whether she's seeing anyone else and if she's keen to see where things go. You'll have a clear answer one way or another, if she wants to keep playing the field it might be best to cut your losses now and move on as I'd say after half a dozen dates you should have a pretty good sense of someone being worth investing more time in seeing or not.
If after half a dozen dates she's wanting to see other people still, I'd take that as her hedging her bets because she's waiting for someone else to come along.
Thanks for the advice!
