Good decision. I would do the same!
I had this girl reject taking my seat at a bus bench. This was on the first day of school before I knew it she was sitting down. That impression of always turning down my offer hurt me, and if I could clear things out I will. Knowing my vengeful nature I am trying to not go back to every emotion that rejection has put me thru. I was suppressed for 10 months, and all that time she was making fun out of me, because I cared about her too much to get away. I post a lot of things on here, and all I want is closure, because I am tired of living that life in poetry. A person can't say, "thank-you for standing up for them, and sit down after being all grateful about it in my face." Later...Trying to repair the damages in good-bye. That's just my rap on your question.
My Ex did that a lot, but she only wanted to be with me for the night. Judging by the time of night she would call, I suspected I was near the bottom of the list, and it was closing time at the bar she frequented. I said no. If it were for a long term relationship, I'd still say no.
first choice not second best
I would question the motive
I would be tempted to say, "What took you so long?" "I'm happy it finally dawned on you what you missed out on."
My old self will take the man back (I've done this in the past). But the new me, absolutely not. Like someone mentioned before, I would question their motive for coming back.
