Since Friday (the last date), he hasn't texted me or called me anymore. On Sunday, I texted him asking how his day was and he said he was not feeling well. Monday came along, I texted him asking if he was feeling better and he said his company sent him out of town for work and there's a possibility he might have to relocate and he was feeling stressed. I called him on Monday and Tuesday to talk to him and he didn't answer my call both times but replied with an excuse that he was either out with his colleagues or doing something. He didn't call me back or initiated a conversation through text or made any future plan to see me. He also mentioned that he'd be out of town again over the weekend, which is when I'm normally free to see him.
So do all of these sound to you like things are over between us or is he that busy to not even text me asking about my day. I thought things were going great up to this Friday so I'm not sure what to do. We used to agree to be completely honest and upfront with each other about issues. Should I ask him what's going on between us?
