I'm 17 and my teacher is 29 . I met my science teacher 7-8 months ago. Those feelings started on January of this year. We talk during spare time, he's really kind and funny, he helps me with my studies and everything, he isn't the kind of sensitive teacher so it was never awkward to be with him until those feelings ruined everything. At first I thought it was nothing so I ignored it but I don't know why every time he talks I can't listen to him because I'm too busy admiring his looks and everything and I'm imagining things on my head where all I can see is myself and him.and I'm really worried cause I can't listen while he's teaching, I don't want my grades to pull down because of this stupid feelings. I just want to study but every time I think of studying it seems like my head is telling me that I have to focus on his subject even though I hate science so that he'll notice me having the highest grade and he'll be happy. I know it's wrong. I tried to stop it but I cant. I know this will do nothing because he's married and has 2 kids. And even if he has no family yet I know its still wrong because he's my teacher and I'm his student and our age gap is hella big. I also stalk his Facebook account a lot, looking on pictures and seeing how happy he is with his wife and kids. Help me.

Set some boundaries of BETTER behavior and stop stalking his facebook. You have chosen a really easy way to feed your fantasy crush, and not only does it distract you, it's leading you down a bad path.

Of course we humans have no control over the feelings we have, but we can darn well fully control what we do about those feelings, and don't have to get carried away with them in unhealthy ways. You may be allowing yourself to get carried away.

Get control of yourself.

If you really care about him , then leave him alone. Even the appearance of anything happening with you is enough to get him fired and basically ruin his ability to work anywhere as a teacher ever again. There doesn't even have to be anything going on.

You want to find a way to make him actually hate you... thats the most quick way.

As has been said, you need to get control of your hormones. If you don't trouble is not
very far down the road. More for him.

Stop stalking his Facebook page, you are only feeding this crush. No more spare time conversations either.
The school year is just about over and I would imagine this crush will be too.
