oneitis a horrible disease.
Especially if oyu get out of a ltr and start dating right away your just looking to replace what you had. I've been there the rebound relationship. You have a great date and already planning the future, will we live together, how long this will go, i really like her etc. All the while you falling into oneitis and she has a profile up on pof and she has another 3-4 dates planned in the next week.
That's why I don't even like dating, i just call them "chill sessions". And I always do what I planned on doing anyways.
Look in all my life I can't even remember one bad date I had, but I've been on numerous dates where the other person never contacted me again or it was just one date and done. Zero expectations if it doesn't work out take it as a blessing.
I mentioned this before I went out with this chick a few times and I was starting to really like her, anyways she stopped replying to my text messages etc. i was like

, anyways i google her name and her blog popped up and she was going through depression and was on pills, i counted my blessings. I didn't want to deal with that, but I would have never known maybe until i got so much more emotionally invested and it would have been harder to cut the cord.
Now if somethign doesnt work out early great probably a underlying reason I don't know yet. Could be she's chatting to her ex, or still in love with him, emotional problems, financial problems etc.
