There are some guys on online dating sites who aren’t necessarily there to find someone to date.
Unfortunately, some guys simply get on dating sites in order to garner attention.
They show interest at first because without doing so, they will not be able to get the attention of the girl that they have pinpointed as their target.
There is something that is now troubling you about a guy that you have been talking to.
Perhaps you have had some conversations with him that have left you doubtful about whether he is straight or gay.
This may really be bothering you because you are worried that if you were to allow yourself to continue interacting with this guy, you may start catching feelings for him that may not be reciprocated on his part.
