What does my boyfriend want?

Honestly, this sounds like a very sensitive subject. If he has some kind of mental illness, then it could just be how he is, but in my experience, any guy who doesn't want to hear from his girlfriend at all, there's something wrong... I'm almost 7 months into my relationship and my boyfriend and I text each other at least 100 times a day. And we live together lol. I don't know girl, this is pretty strange. Try talking to him in person about how you feel and maybe he'll tell you what the heck is up. Good Luck :)
