All depends man, theoretically, it's just "ok, let's forget about this.." and move on but if you are starting to be in love with that person and that person "betrays" the trust you put into her.. and on top of that you were like more than a year without flirting with anyone after a harsh break up/divorce, then it's pretty fucked up for one's self-esteem, don't you think? I mean, there's super stoic people who would just say nah, it's not a big a deal, but it's pretty crooked to being ghosted in certain emotional settings.
I'm again not sure if this girl I talked about it's ghosting or not, now I care less about it, but the first time it was hard to be waiting several days, now it's like I threw all the cards in the table (it's an spanish expression, something like being all in) because I sent her a karaoke of me singing a good song of into the wild film, and some photos, so it's like, if she doesn't reply to that, it's totally clear that I was being too "risky" in this bet and it wasn't meant to be.
I always play hard with someone I think I could love, I'm not one of those people who wait too much to go all in if I see something special in a girl.
I feel like an adolescent again, to be honest.... haha
