Within any relationship, it’s hard to be 100% happy, 100% of the time.
I believe that no matter how confident one may be, any average dater will usually come to a point where they have doubts or insecurities when in a relationship.
Generally, it can range from nit-picky aspects you wish you could change about your significant other, disapproval for how they act, anxiety of being not good enough for them, or weariness on where you two will be in the future.
The list goes on, and I haven’t even gotten into specifics!
It’s hard enough going through the rough points of a regular, offline relationship but imagine if you had these doubts (and honestly much more) while being in an online relationship.
