Pisces ex-lover returning into my life?

Hi there! This is my first topic on the forum.About my situation; I had a pisces lover just before I have got separated from my husband. I really loved him and we were planning a future together. However the situation at the time of the separation got complicated so I finished my relation with my loving pisces man too😢.it really did leave me heartbroken and I was told by many of our friends that he was suffering very much too. So after a year without contact he called me and a few weeks later we went out for a date. We had a nice time and kissed. I think he really enjoyed himself too. Now there are a few things which make me crossed: the communication. He hardly ever calls me or starts conversation😢.however if I call him he would be sweet and trying to arrange us to go out. I cant understand?if I like someone I would like to communicate with them?!now he will come to mine in two days for a coffee and then next weekend we go out for a dinner....and I am clueless how I should behave around him...shall I call him in every few days if there is nothing from him or shall I stay distant as he does sometimes? When we are together how shall I behave? I am a gemini he is pisces... Anything good coming out of that?
