Most Helpful Guy
He told you what's going on with him.
" He said his life has been really stressful lately".
His life sucks right now. He knocked up a girl and lives with her in a new town and doesn't like life right now. So he called up his ex girlfriend.
I mean, maybe he simply feels guilty for how he treated you and wanted to apologize for it, so that he could be relieved of guilt. But he went on to vent about life. So it's not about how he wronged you. It's about him wanting something. Maybe he wants you for emotional support. Maybe he wants to runaway from the situation he got himself stuck in and an easy out, would be running to his ex.
It doesn't really matter. What matters is what you want. Because this looks like bad news and staying in contact with him right now is a bad idea for you.
