<human>: Hello /r/relationships

My girlfriend and I have been dating for 2.5 years. She has a good guy friend that I don't really care for, but he makes her happy so I deal with it. They text all the time, and smoke weed all the time. They hang out about every other day.

For some more background; my girlfriend has been kissed by 2 guys in the past. She does not text these guys anymore, but occasionally she does see them. Not often enough for it to matter.

Saturday my girlfriend told me that her good guy friend (Lets call him Jake) confessed his liking for her. After a lot of questioning she said he tried to kiss her. Then after more questioning, she told me he did kiss her.

I was willing to have her just not text Jake and hang out with him all the time, but after knowing he kissed her, I don't like this. The thing is that Jake knew she is dating me. I have met him before, but he crossed a line.

She said she is not going to cut him out of her life, but I love her and still want to date her, but I don't know if i'll be able to handle her always texting him and hanging out with him like nothing happened.

Also it should be noted that she does not want to cut off contact with him because he is a great friend AND it will mean she loses the friend circle. This guy is always with some of her other friends, and they will not be able to hang out without Jake in her life.

What do I do?

Could you distill the essence of the text into 1-3 sentences?
