If an ex responds to your text are they just being polite?
well, depends on what their response is
Agreed with Ed.
if they text one to five words only answering questions. then yea
No... They are your ex... When you text an ex out of the blue and you receive a response, they usually have a hidden agenda...
Most likely your ex has time on his hands and has time to talk to you meaning he wants to hear you out and see what you want and cares about you still to even reply back
