In Love With Two - Help!

Hello, I have a friend of about a year and 3 months. The relationship with him is actually quite complicated almost from the very beginning, he is bigger than me, more character - an absolute critic. It's always been hard for me with him, he's a difficult character. For the first time because of him, I accept that he goes out with other girls, even though he knows it hurts me, he says I have to trust him and that they are his friends. . He has often criticized even insignificant things in me and this has made me tense around him over time, I feel a big hole in our relationship, and I really owe it to him. Very recently we had a very serious quarrel, she was even separated for a short time, and I went out with an acquaintance, we liked each other a lot as characters, then we went out a few more times, we wrote to each other because he was studying in another city and I started to feel very strong. to him, then we met again several times and he admitted to me that he had feelings for me and I confessed to him. I get along really well with him, I feel myself, really calm, he's not with my friend. He seems to be the good boy while my friend falls for a bastard. My friend and I recently met, but this boy is out of my mind, please, if anyone has been in such a situation, give advice. It's really hard for me, I feel bad, I can't just give up a relationship in which I've given too much and seen my future (to some extent, though difficult) And now when a person appears with whom we have a lot of similar characters and honestly I think I will be happier, I don't know how to act ....
