She is looking for someone who lives closer to her.
Long distance relationships can be very hard to maintain.
Being that you aren’t in the same physical vicinity as your long distance girlfriend, it can get really hard for her not to have someone close by that she can turn to when she is emotionally in need.
As your long distance girlfriend, she is going to have moments where she just wants someone to cuddle with or become affectionate with.
Being that you are not physically there, this would be impossible for her to have.
She may have initially been excited about becoming your girlfriend because she really liked you and was hopeful about the future.
However, if she has now been your long distance girlfriend for a decent amount of time, the reality of her relationship with you has most likely set in.
She may be coming to the realization that this long distance relationship approach is not going to be as easy as she’d hoped.
In essence, the initial excitement that she may have had in becoming your long distance girlfriend may have worn out or is in the process of greatly dissipating.
She may know that she longs for physical interaction now more than ever.
Hence, your long distance girlfriend still goes on dating sites because she may be hoping that she can find a guy who lives closer to her.
She may have initially started doing this reluctantly.
Knowing that she has a long distance boyfriend in you, she may have felt a sense of guilt whenever she went on dating sites.
However, as she has more and more of these moments where she just wants physical affection, she may have found it that much more difficult to keep herself from going on dating sites.
The first time she did it was most likely the hardest.
However, as more time has passed and the both of you have remained in a long distance relationship, she may have found it easier and easier to go on dating sites.
Hence, if you have noticed that your long distance girlfriend still goes on dating sites and this has persisted for a while, there is a good chance that she has reached the point where she is not even feeling guilty whenever she does it.
Another reason why your long distance girlfriend still goes on dating sites could also be because she has noticed that you are on dating sites as well.
Oftentimes, a person will react in this way in order not to allow themselves to get taken advantage of.
If she has noticed that you have been active on dating sites, she may feel the need to go on dating sites as well just so that you don’t end up blindsiding her.
She doesn’t want to be a victim.
She may want to make sure that she also keeps her dating options open if she notices that you are trying to go behind her back by going on dating sites.
You may not have taken into account the possibility that she has also been watching what you have been doing on dating sites.
If you have maintained active accounts on dating sites, she may have noticed this.
Even if you haven’t been as active on the dating sites since the both of you became exclusive to each other, she may have still noticed that at some point in time in the last few weeks, you logged into your online dating accounts.
This may have made her fearful that you are trying to replace her.
As a result, she may have also started going on dating sites in order to avoid being left behind and replaced so easily.
In essence, she wanted a backup plan.
If you have recently logged into dating sites, there is a chance that she may have actually noticed this and is now responding to that by still going on dating sites herself.
