I think im in love with my nerdy but cute math teacher what should i do please help need guidence?

ok im 14 and my math teacher is 30 hes recently married and has 2 soon to be 3 kids his wife is pregnant with his supposide first child.the ***** proabably cheated on him she has been married before oh yah forgt to mention he married into the other 2 kids. Anyways i really like him and i think he likes me to.hes really nerdy but sweet.hes not a perv or anything like that like some of my other teachers who look at my boobs. He has my back and i have his and i can tell him anything we get each other. Should i tell him i like him and have him reject me and think im a weirdo for the next 3 years of highschool or keep it to my self and always wonder what he might have said? I wont see him till after summer vacation. And he probably wont be my teacher because i dont think he teaches sophmores? My mame is not jack p what kind of bullshit is that.just thought id let u no after all your helping me. This *****!
