Your ex may not have known what to say at that moment.
They may not have been expecting to find you on a dating site.
When they viewed your dating profile, it may have been out of impulse.
They may not have known exactly what they intended to do if they were to view your dating profile.
Hence, they may not have sent you a message because they just didn’t know how to go about reestablishing communication with you.
Your ex may have been worried that you would not reply if they were to send you a message.
They may have also worried that if they were to send you a message, they would be indicating that they aren’t over the breakup.
Your ex may not want to give off that impression. However, they still couldn’t help but view your dating profile.
They may have suddenly felt a rush of emotions when they first came across your dating profile on the dating site.
The image of you may have triggered memories of their relationship with you.
They may have thought about certain activities that they engaged in with you during that relationship.
They may have thought about particular moments that were really memorable in a good way.
Hence, your ex may have allowed those thoughts to get the better of them and viewed your dating profile as a result.
Again, your ex most likely didn’t know what they would do upon viewing your dating profile.
Perhaps they just wanted to get another look at you.
They may have wanted to read what you had to say in your bio.
There may have even been an innate desire to find out whether you wrote anything in reference to them.
They may have wanted to see your pictures.
Perhaps they wondered whether you would have posted pictures that the both of you took together or whether your appearance has changed in any way.
There may be a good number of curiosities that your ex had in viewing your dating profile.
However, at the end of it all, they didn’t send a message because they simply don’t know how you feel about them and don’t want to give off the impression that they haven’t moved on from you.
Your ex may feel more secure in you messaging them first.
This may have also been a reason why they viewed your dating profile but didn’t send you a message.
Being that they simply don’t know whether you are still into them and they don’t want to make themselves look desperate, they may have viewed your dating profile in the hopes that you see that they visited and send them a message first.
They may simply not want to be the one who initiates the message because they don’t want to deal with the sting of rejection or the possibility that they would come off as desperate.
When your ex viewed your dating profile, they may have wondered whether you have met anyone on the dating site.
They may have wondered whether you are dating a bunch of people.
Perhaps there was an initial desire to send you a message but the thought that you could be dating a bunch of other people may have stopped them from doing it.
They are insecure about this possibility.
They may not have had much luck in finding quality people to date on the dating site.
If they were to message you and discover that you are going on some great dates with people, it may truly dampen their mood.
They would get the sense that you are succeeding in moving on while they are still unable to find dates and appeal to people.
Perhaps they just want to keep themselves believing that you are having a hard time finding dates as well.
This thought may give them a degree of comfort. This way, they know that they are not so easily replaced.
