Search Results: guys meaning what they say

This guy in my school likes me, he makes it pretty obvious. Meaning he is always with me and if another guy is near me or looks at me he glares at them and puts an arm around my waist. To me he seems like a stalker, he comes into my lectures (that he is not in) just to say "hi" or to see if i'm okay. he also wants me to go to his house all the time. He will be like, "if you're not doing anything or if your bored you should hang at my place" I offer going to other places like the bowling alley but he gets angry and is almost demanding me to go to his house. He asked me out a few times but i declined his offers because i don't want to be like that with him. But here's the problem, on my social media whenever i post something literally a minute or less later he likes and comments on it. On facebook he will post on my wall a whole paragraph about how i'm "such a wonderful woman". He does that once a week and it's a little strange to me. He wants to know where my apartment is so bad. Every chance he has he wants my address, i always say no. But the latest problem that happened today with him was this: he asked me out again, i said no but this time because i have a new interest in someone else. I told him this and he went off! he was saying the classic "if i can't have you know one can!" and i was apologizing to him about all this but he didn't have it. But what concerned me was that he is threatening suicide. That really got me and I was telling him that is a bad idea and he can have other girls not just me. but he told me that, he wants to get married with me, have specifically 3 kids with me and he wants to be with me forever. that creeped me out big time. So in all this guy: really likes me, got angry when i don't want to go to his house, wants to kill himself cause he can't have me and he wants to marry and have kids with me.

so what's up with that guy? what do i do?
