<human>: Provide a brief overview of the text.

I'm having problems with my ex. Yes he's my ex. I had broken up with him because he had trust issues and you can't have a good relationship without trust. So I ended it with him. As it turns out I started missing him, and I asked him what he would say if I asked him out some day soon, he said he would say yes. So since yesterday ( Sept. 29th, 2016) We've been unofficially dating, we've kissed and hung out every day after school for 2 weeks. Me and him are in this club together he's a senior I'm a junior, and he's the president of this club, so he's required to get the phone numbers of new members. So my ex got the number of this freshmen and they've been texting a lot recently, more than he and I text. Today he confessed he was into this freshmen but that she doesn't like him back. I was gonna ask him out October 2nd. But now my plans are postponed and idk if I should stay with him or just forget him. If he really loved me there wouldn't have to be a choice. He says he loves me and only me but I don't believe him.
<bot>: My future senior boyfriend has feelings for a freshmen, swears he doesn't like her anymore, should I stay with him or not?
