How do I react to this?!?

I'm currently in year 11 and 16 years old, I have a boyfriend who is almost 17 and we have been dating for 18 days.

At the start of this academic year a boy in year 10 (we shall call him H) (15 years old) joined the school, I was actually quite interested in the boy at that time but after him showing no interest I also lost interest in him.

Recently I have noticed that H has been spending a lot of time looking at me and has been making more of an effort to talk to me and start conversations. H is a ver nice person and he is polite and friendly. Even more recently the staring has became very intense and after accidentally making eye contact with the stare I can see that it also have a very sexual connotation to it.

My best friend has also noticed it and she is on the same bus as H, she has also said that H has been making a conscious effort to be nice to her since he knows that she is friends with me.

I received a text from my friend yesterday saying that H had pranced onto the bus holding a bag of condoms after lying to the school nurse about having a 17 year old girlfriend, he then proceeded to asking her if I was single. After hearing that I was not he looked disappointed and then asked how long we had been dating , stating that "there is time yet". My friend tells me that he obviously got the condoms with the intention of using them on me.

How do I deal with this situation? My boyfriend feels threatened by H. Would it be possible to hold a friendship with H?
