TLDR; Got a number after some flirting, kino, dancing. Her response next day was not really looking to hang out now and not sure how to continue

I have not went out for a WHILE... 4-5 months not drinking or barring been busy with stuff going on at work and family & was also getting over a bad breakup so I finally was invited out with friends (2 guys and a girl plus myself) in the city over Halloween Saturday;

Anyways we go downtown, are drinking a decent bit and admiring the awesome costumes meeting some cool people. One of my friends Jim gets about 3 numbers at this one bar and we're just gawking at all the nice nurses and barbies out everywhere. Me and the other guy wanted to get into the action too so we go meet up with Jim's coworker and friends (5 girls) at another bar. They're dancing in a crowd when we get there so just go up and join the fun... 3 of them are attractive to me so I just go ahead and pick the 2nd because 1st in my mind was a perfect 10 (and something I was out of shape for at the moment). We uber with the girls to a second spot for better music and the one girl I'm dancing with get to talk a lil bit, roleplay the costumes so naturally sucking and biting comes up... establish a bit of kino. At the next/last bar we are dancing more and grinding now and it's pretty dark/late so end up doing that for a bit before last round is called. I didn't realize it was that late and the girls are all taxi'ing home together so go to get her number before she hops in. I realize it's 3AM (lol daylight savings time). I know it's important to get the # on a high but I just did it right before she left and considered that a success in the least. Texted her my number and something forward again about the costumes/dancing and said would like to see her again. No response but later the next day she says she had fun, see eachother soon with emojis and the dreaded "not looking to hang out with anyone right now."

Not sure if I miscued some IOIs or if she was actually sincere, but am personally thinking the "really" in the girl's mind means she is not sure herself, or is pulling to see what I say in return. Plus the coworker (her friend) said to Jim (my friend) that she thought I was nice and into her... seemed like they obviously talked about it since the text.

Basically out of shape, not sure how to respond, try and meet solo or get the 2 groups back together to push anything further, or to say lost cause and not respond at all.
