is she putting her guard up even if it seems like she's interested in me?

a while back I was dating this lady, we have a lot in common so we mesh pretty well. At a point it felt like I had to put forth most if not all the effort (calling, setting up plans/dates) it felt one sided so I stopped talking to her but we're talking again recently. The other night I was straight forward with her & asked her why she seemed so hot & cold at times she seems into me & other times she seems unsure. So she asked if i wanted to go grab a drink the next night. So we went out had a nice date, ended with a kiss, held hands so the attraction is there. When I was talking to her last night i was asking her what her plans were the next day & it feels she doesn't invite me in them (like lets grab food or whatever). I never invite myself either so I'm wondering if I shouldnt text/call her for a day or so to see if she hits me up in return? what do you all think?

p.s. - im not into playing games but maybe give it a few days and see if she reaches out to me
