MAN TROUBLE!!!

Thank you all for the advice, I’m actually taking it, it’s hard but there’s no point holding on to something that’s not mine right.
Went to school yesterday and they told us our project deadline is 12th, that’s less than a week away, this is after telling us we would have till the end of November, I hate these people for thinking they can be changing their minds like it doesn’t affect peoples lives, well, I got to step up my game, so my project will be done next week.
I have this friend who’s in a relationship with a guy who (u guessed it) has a girlfriend (this thing is going around these days). Anyway it started like this, the guy was chasing her for a while and at first she wasn’t interested but after a while, she relented. Apparently, at that time, he was having issues with his girl, his parents didn’t support the relationship being that they are both AS. The thing has been going up and down for a while, sometimes she’s happy and sometimes she’s sad. Some days back, while he was asleep, she checked his messages and she saw this, “I and girlfriend are going to the registry on November 10th, blah blah”. Apparently, they decided to do it without their parents consent, she didn’t say anything to him, she just went back to sleep, when she called to tell me, it was sounding like Nigerian film to me.
A day or two later, she had this conversation with him,

Girl: what you doing on your birthday (November 10th)
Boy: I don’t know, nothing really
Girl: you sure
Boy: yea
Girl: I heard you are getting married on your birthday
Boy: where did you hear that from?
Girl: somewhere
Boy: I was supposed to but I’ve changed my mind but I haven’t told her yet

He then proceeded to explain to her that the girl is actually SS and the only reason he wanted to go through with it was cause of guilt and they talked and talked. I don’t know if she should believe him, what I told her though was that we should wait and see what happens on November 10th and then they can go from there. What do you guys think???
