I (18M) have a crush on my friend (18F).

I have this friend. We used to study in the same school for 2 years but during that time, we didnt have any kind of convo, but after entering the same college, we are interacting better. Our parents have become a bit close and once I had gone to a trip with my parents, there I had even bought a gift for her. Now she is very beautiful and I like her personality very much. I had developed a crudh on her since the school days but during that time, i tried to control my emotions for my academics. But the thing now is, there is another guy in out college who is trying out on this girl. And he is better looking than me, and after our internal exams got over, he asked her to go for an eat ( not dinner, but casual). Recently I had a convo with her, she said that there will be rumours going around about her and that guy bcoz many people had seen them, and told me not to believe in them. When I asked if she is interested for a relationship, she said she is not thinking too much about it now, and maybe later.

Now we are sharing a lot than we used to, but the thought that the other guy is putting so much efforts is making me jealous, not gonna lie. I have never been in a relationship ever in my life and this is new for me. And i feel scared when putting a bit more efforts on her, afraid if she takes it the other way.

What should i do in this situation, how can i attract her more towards me ?

TLDR- i have crush on my friend and another ‘better-looking guy but dont know about personality’ guy putting more efforts on her. I like her personality very much
