He doesn't make me his priority

So there's this guy which is my EX, we been talking for awhile aleast for the past two month's up till I told him I truly felt. About how he doesn't make me feel like I'm his priority at all really. I've always been going out my way to contact him and he usually reponds back to me. But at the same time I felt tired of going out of my way for him. We were together for almost 5 year's and I was the one who broke thing's off with him for a reason. He was taking the time out talking to other female's while we were still together and here I am been thinking he's doing it again. But we both also have had deep conversations which was back in March we talked about getting a place together & everything and now it's August. I'm not so sure what to think of him anymore. I pretty much told him yesterday that I felt he was taking the time out for me like I been doing with him. And now he was going back to not talking too me after like 5-6 days with him not contacting me. So I figured he would at some point try and contact me up till I told him how I really felt about him making me feel the way he does. I was always the one trying with him even when we were still together but his lack of efforts aren't showing me much at all.
