How to tell him I like him??? DESPERATE!!! HELP?!?!?

Feel him out first. Flirt with him a little and see if he gives anything back. Text/talk to him just a little bit more. if hes responding and flirting back, keep goin and do it just a little bit more. dont rush it, take it slow. if hes not into you, hell back off when you start texting him and flirting. you'll notice him distancing himself if hes not into you. but if hes good to go, then keep goin and eventually you two will just know. it takes time, but if you really dont want to ruin a friendship and not sure how to go about, you have to go slow and just feel him out! good luck!
