Does he care?

We've been together since high school. We had basically all of our first together. He makes me so happy and I make him happy. He talks about a future with me all the time. He even wants to have another baby with me one day and is excited about it. I feel guilty for worry about small things he sounds like Prince Charming lol. He is Prince Charming sometimes. We don't stay mad at each other for long he'll hold me until I'm not mad anymore or we just end up talking because we can't go long without talking to each other. Here's the dark side he cheated on me for a year with one of his girlfriends while we were college. I got pregnant and he tried to leave me stuck and stay with her. I don't know he was scared or something. I know really stupid to stay with him after that but I did. Went through like 2 years of him texting her behind my behind my back saying he missed her. I stayed because he said he didn't want to be with her though. We got through all that and he hasn't really talked to her until recently. He went to go see her and he lied about it. We had a agreement I told him if he wants her she can have him. So why would he lie about it? We tell each everything. I'm really hurt. I went through his phone(I know I shouldn't have) I never told him. I asked him to unlock his phone and freaks out. Finally after two weeks he confesses and he tells me it's none of business and it's not relevant because he's over her and he met up with her for closure. I can understand but whenever I try and tell him how much him lying about it hurt me he just seats there and changes the subject. I asked him," don't I deserve closer?" He never apologized for what he did to me he never talks about it but he used to talk about her all the time. Does he really even care? It's like a nightmare everything was perfect two weeks ago until I reopened this sore. Why does he talk about a future with me, a life together, and kids? I don't understand what a forehead kiss means when I'm asking you to tell me how much you care about me. He says some really harsh things to me sometimes but he never says sweet things to make up for them he just gives me forehead kisses or holds me. I don't even know why I'm so upset. Does he care or is our entire relationship a lie? Is he right am I overreacting? Why won't he say anything to comfort me? I even started crying in the car and he just seats there. Of course I got a forehead kiss later.
