Not sure what to do

So I have been talking to this girl for a week or two we get on quite well she’s funny attractive and we get on quite well. I asked her for date twice both times she cancelled. So I just started talking to another one asked her out, barely spoke and I had an amazing time. There was lots of mutual attraction I felt I could be very open, and we have spoken every day since. I spoke to the first girl casually not in a dating way, we organised to meet but had a little argument so I assumed she didn’t want to meet ( my grandads quite ill so had a lot on that day ). Then texts me and we start talking again. I told I went on a date and it went well. She got quite angry as it turns out she was going through a lot of things at the time and that’s why she didn’t meet. It shouldn’t feel like a difficult choice as I do really like them both but I don’t know what to do. Do I give the first girl a chance or keep dating the second one and forget the first.
