Is there someone else?

So I have been talking to this woman a couple months, we have seen each other 4 times, first two times was at her house, but now we have to meet she says she don’t want her ex to see a vehicle in the driveway because he helps with her bills. But she will carry me to her house but we normally meet at like 6 and date normally over by 7:30 or 8. She has canceled on me many times and only sees me one day a week. I feel like she is also seeing someone else but will not say, She will carry me to her house but seems like when she did she wanted to get me back to my car when it got to be 7:30. It’s just weird that first two times I could go there but now she has to meet me, she calls me paranoid I’m I really look at all the things that are gone on, also she says she really likes me but sees me once a week and sometimes moves it to the next day or the next day but can see me only once. I feel like when someone really likes someone they want to see them as much as possible unless there is someone else then things are always screwed up. I’m I wrong to think that?
