<human>: Could you distill the essence of the text into 1-3 sentences?

So, my friend, we'll call her E is currently in college and is a relationship with a guy, we'll call B. I gave her my side of what I believe she should do, but I figure some extra input is welcome. I asked her if she would like me to do this for her so she can get an idea, plus she doesn't know what this place is.

So, they are both the same age, 20, same college, and have been together for over a year, and she's fallen deep with this guy. Her problem is they have slacking communication, and she doesn't like that he smokes pot. It caused them to break it off once, but he said a bunch of things along the lines of "im on my knees, BEGGING you." "i need you" "ive realized you make me SUCH a better person and u make me want to be better""i love you sooooooo much... more than you have ne idea!" "uve been the only person that makes me want to better myself" "i realize the majority of my friends are bad influences and u help me realize that i like life better sober" etc. To which she took him back.
But since they have been back together he has been on a hitchhiking trip and they have barely talked at all, and she is wondering if it's worth her time, she has also said she deserves better, to which I, personally agreed to. She's already deleted his contact info from her phone and is in the steps to break it off, but she wants some extra help. Her other friends don't really know what's going on and even if they did, they wouldn't be of much help. So I come to you, Reddit community, in my friends time of need to lay on some advice, suggestions, ideas, and anything else.
<bot>: My friend would appreciate advice on weather or not she should stay with her current bf, who barely communicates and smokes pot.
