Hi Anni,
Indeed he may be hiding his feelings from you.
However, his feelings may be really conflicted.
There may be a romantic interest from his past of whom he is still emotionally attached to.
This may have been why he told you that he wasn’t ready when you confessed to him.
On the one hand, he has shown that he is attracted to you by staring at you constantly in the gym.
However, on the other hand, he has shown that he is hesitant in developing any kind of romantic relationship with you through the way he cut off contact with you after 11 months of knowing you and how he stated that he only sent you a message on Facebook by mistake.
He may be worried about the potential for being hurt if he were to get into a romantic relationship with you.
But that notwithstanding, there is still a part of him that doesn’t want to let you go entirely and wants to keep you in his life in some capacity.
The best thing to do at this stage is take a step back.
You are always the one reaching out to him.
You need to stop that.
Avoid eye contact with him at the gym.
Whenever you stare back at him when he looks at you, you are showing him that you still care.
Hence, he just feels like he can continue acting in the same way he has.
You need to give him a sense that you are moving on and not really going to be receptive to the way he stares at you in the gym.
If you start avoiding eye contact with him at the gym and become friendly with more guys at the gym, he will notice it.
This will most likely scare him into thinking that you are moving on from him.
He will realize that he will not be able to eat his cake and have it too by constantly giving you mixed signals.
This is often what will force a guy to act by either deciding to go for the girl or just ditch the games and move on.
Either way, you would put an end to his confusing behavior.
