Search Results: weird text messages

We got into a bad argument a couple months ago after a weird period of us being really distant from each other, and he admitted to being so frustrated he thought about hitting up other girls, but never did. And since then he's been talking to this girl he knows 24/7. I'm not exaggerating when I say there is a notification that she messaged him every time I get a glimpse of his phone. But whenever I told him about how uncomfortable it made me he told me I was being selfish and paranoid and that she needed help because she's struggling with all these different problems and so on, and would continue texting her constantly. I had kept noticing the past two months or so, whenever he'd hand me his phone for whatever reason he'd always delete their DMs before handing it to me. And last night I had finally had enough of that and called him out. I was more mad that he thought I was actually stupid enough not to notice him do that so often then I was about him talking to her. And he kept listing excuse after excuse and kept saying he wasn't lying since they weren't doing anything and I have no reason to be mad and blah blah blah. But he is STILL talking to this chick non stop. And it really bothers me that he uses him knowing her from school (for less of a time than I knew him) as an excuse and will completely ignore my discomfort. I understand he's gonna have female friends and talk to them, I have male friends. But I don't understand why I'm in the wrong for being uncomfortable with him repeatedly crossing the boundaries of my comfort. He claims I'm violating his free will but I'm not asking him to drop communication entirely. I just want him to be mindful of how I feel and take that into consideration before going out of his way to start a conversation every day.

So I've met this guy 4-5 months ago and since begining acts different than other guys in our group of friends. He had problem talking to me, he was staring at me a lot and smiling, when I would ignore him standing next to me he would become mean and stuff.. and always was near me wherever i stand. Last 3-4 weeks he's been really distant in person.. he would smile anymore, won't stand near me and other stuff he did, but he always wants to help me. We have group chat with two more guys, and my guy friend said that him and I text almost always in there. We tease eah other, he compliments me and we sand each other hearts sometimes (most are between us).

So few days ago he called me on app and me and my friend didn't answer and he said that we should give him our numbers and i sand it to him in private box. After two hours he texted me and I tried to continue conversation but it died quickly (I have his number for month and he has mine but he acted like he forgot about it and he sent me text). He stopped to talked on wapp and answer to my text on group chat from few hours ago and i ignored it. I ignored him for 3 days and today I tagged his friend and asked him something and this guy answered in second for friend, and he did it twice.. and he wasn't even online when i sent message in group chat.

I don't know what's whit this guy. I think he might be like me but im not sure. Two weeks ago we were for 5 minutes alone first time and he was so quiet until his friend came and i don't know why.
He's nice guy, but I don't know why he won't talk to me in private box or when we are alone. He's really sometimes weird. What should I do?
