Love questions

Things are changing at my love path, finally actually. Since a month or three I totally forgot about my ex, after 2 years. And I am thinking he forgot about me as well. There’s this new person, I’m just going to mention his name, Simon. And now that I am really in love with him (it took me some time ofcourse because I am a very slow type) I realize how wrong my ex was for me, and I am so happy I got out of the vicious circle socalled "our love". And this boy I am in love with, he knows I am and he’s in love with me too. It’s just a bit difficult so I am going to explain. I have known him for 2 years now. I used to see him in summer when we both went to the same youth movement but back then he just got together with a girl he dated for a total of 15 months or something, and I wasn’t interested in him either, even though I already heard people say he found me pretty back then. Last year December, they broke up because the girl wasn’t in love with him anymore and he was heartbroken. And because I broke up with my ex almost simultaneously he told me he broke up and I told about my ex and we could share our stories and fix eachother in some way.Then we sort of lost contact and he started dating another girl for 5 months but I didn’t bother because I still didn’t have feelings. I think from January till June or something they dated. And coincidental, my now best friend (a boy) who I was just getting to know back then in June, threw his birthday party. And COINCIDENTAL he is Simon’s best friend so Simon was going to be there too. We didn’t talk that much actually, but since that party, we talked on Facebook again and during my final exams end of June he told me about the girl he was dating for 5 months and how jealous she acted without reason and how he didn’t know if he should carry on with her. Meanwhile I was having exams, and staying up late every night talking with him while studying, but I didn’t mind. (My grades ended up well anyway). Somehow I just couldn’t stop talking to him. Although I never started the conversation. I don’t know why, I am a strange person. But then during summer the contact got a little less again, but never stopped. Then school started and during lunch I saw him always sitting on the bench in front of me looking at me. And because my contact with my best friend became better and better, I got to see him more and I slowly began to feel something for him. He was so sweet to me compared to what my ex was like. He told me all those sweet things and he is very sensitive, yet funny and just lovely. He is open about everything and I think I can truly trust him. The only thing that is standing in the way is that, since almost 2 months my best friend and Simon are in a fight. I don’t know what the hell happened but clearly something happened. The one blames the other. They don’t hang anymore in their spare time and I am too shy to see him alone. I am way more comfortable in group, but he doesn’t want to be in group, because he is in a fight obviously. I decided to let their fight be and trust on it that if their friendship is strong enough, they will survive. Because I tried very hard for them to make up and still it’s not how it has to be. I shouldn’t have stuck my nose into it but I just didn’t want them to split up for two reasons. Now I think I will have to push my boundaries and just go on a date with him or something, because my feelings are really really strong and he really wants to see me so after my exams during the holidays I am going to do something with him, I don’t want to lose this. The only thing bothering me here is: should I just do everything at my pace or is this really a boundary thing and should I just go for it? After all I’m not too experienced when it comes to love. I hope I didn’t explain it too difficult.
