Does my daughters mother still want me?

ok so here is the thing. Me and my daughters mother have been together for 5 years and we have a 2 year old together. Ok, I put myself on child support, I call my daughter up twice a week, and I see my daughter every week to spend time with her. I do all that I can to have my quality time with my baby because I think its important for a little girl to have her father in ther life. However, when I do stuff with my daughter I do it on my time with her not the mother.... so yesterday I get a phone call from my Ex and she was telling me that I should come over the house to see her more. He excuse was because they have a swimming pool and so on. I told her that the place were I live has as swimming pool and play ground too... but she kept on insisting that it would be better if I came around to see her at her house. Now Im not going to lie... I still love my EX she is the mother of my child and we were to be married... but my question is why does she want me to come over to her house to see the baby when I see her irigardless, it doesn't matter where my and her spend time together its still quality time. Is this a ploy for my daughters mother to maybe try to get back with me, and is this a sign that she still want me? Ladies a little clairty.
