After being with my partner for 3 years I got dumped out of the blue by text message, with him saying he wasn't happy but no more details other than that. Then total silence. Took me 6 long months to even start getting over him when he popped back up. Foolishly, I met up with him and we started seeing each other once a week. This has been going on for nearly 3 months now. Over the last week he's been taking longer to reply to my messages and now he seems to have stopped replying altogether. I knew it was risky starting things back up again but (naively) I didn't think he'd sh*t on me twice. I'm unsure whether to text him and ask for an explanation. I never got one all those months ago, and I didn't ask for one either. I'm feeling so upset, surely I deserve to know why he's done this again?!
