Relationship

So I met this guy on thanksgiving 2016 at a friends place, he asked me friend if he could befriend me and my friend was like sure why not. I work in the doctors office and during the same week, he happed to come there to do physicals for his kid brother for school. On the day for the to pick the result, he took my number and we started talking as friends. We go on dates and have fun as besties. He had a serious girlfriend in a different country and a side chick in the US. After some time, we became more close, he asked me out but initially I don’t want to but as he kept on persisting I decided to give him a chance. I made out with him and witching sone weeks he broke up with the side chick. So it looks like am the new side chick now lol. I made him know that am not comfy about this whole thing so we should stop. And you know guys and the way they talk in times like this. He assured me that am gonna be the only one so I should give him sometime to sort stuff out with the girlfriend. I was just confused because I said to myself what if he get rid of me just the same way he is doing now. But hey muted and watch what was going to happen. As times goes on from time to time I ask Whatsup with him and the girl but anytime u asks he gets moody and asks me where this is coming from. He makes it look like I spoil our moods whenever I raised that topic so I quit asking. He made it looks like am the only one which I kind of believe until he started giving me attitude and I found out from the mum that he is at 90% close to getting married to the long distance boyfriend. That day, while week and month was terrible. I just couldn’t control myself. When he find out that the mum has revealed this to me, he kept on blowing my phone with calls and messages and calling my friends. My friends advised me to hear him out and get the whole story clear which I did. He explained everything to me and promised me he was going to go do everything to make this relationship work but later on he came back to tell me that he is going let both of us go. I weeper and weeped but after we had a talk we decided to let things flow naturally and we came back again but things was not as it used to but after months it gets better than before. But I realized he still talks to the ex but when confronted him he told me if he talks to her that doesn’t mean he is going out with her, which I decided not to talk about it again. Ending of last year he started acting cold towards me and anytime I complain he makes it seem like I complain too much so I decided to ignore certain things that he does even though it has to be addressed I will ignore. But recently I decided to confront him because it was too much, when I call him is like he is mad talking to me, he drags his feet to reply my texts but he is someone who is always on his phone. He claim if he doesn’t reply my text it means he is busy. When I confronted him through text he said all what am complaining he doesn’t notice anything wrong and therefore is a new year so he is not ready to go back and forth with me and therefore this year i should talk to him more Concerning our business (because I have a business company with him). From that point a whole lot was going through my mind. Idk if he is trying to tell me that he doesn’t care about this relationship or he is fed up or he got back with his ex or what. I decided to be strong and give home the space he wanted. After two days of us not text, talk or see each other he text me on the third day like “bae sup, how you doing?” I ignored him the next day he texted me to let me know he purchased something with business card and I replied no p. He then text back asking why I saw his previous message and ignored him. I don’t reply. Just yesterday night he send me emojis saying “he is thinking about me, he loves me so much and he wishes me a good night” I read it but don’t reply. Like seriously, what does he take me for. Am so confused right now any advice for me please. I know is long ass post but please share your thought....
