I know exactly how you feel. None of my friends ever understood me either. Now they just except it. All my friends would have one boyfriend after another. And I would have none. They would say that I was too picky. But how can you be with someone when everything inside is screaming " he isnt right for you"? They could never understand how I could know if they were right for me or not. And honestly I couldnt either. Sometimes I would feel that a certain person can help me get though something and I could help him. That this relationship was temporary but helpful. I used to hate that I was so " picky" but now I accept it. Its a part of me, and i am glad that I have this gift if you want to call it that, because it saves me and the other person a lot of pain and time. It isnt something that you can change or turn off, try to accept and use it for good.
As for your relationship right now.
As empaths, we feel more deeply. That is why the excitement is so hard to tame. Its like you know that what you have with him on some level is " right". You can feel it. You may not know it but your not as scared to reach to him, give yourself to him. But he is. He is scared. He doesnt feel as deeply as you do, he doesnt have that " it feels right feeling". You have to be patient with him. Remember that he does not feel at the same depth as you do. But that does NOT mean that he does not feel the same way about you. It will just take him a bit longer to get there, to let himself feel so deeply.
You see maybe im wrong, but loooking around we as empaths dont have a choice how much we feel and what we feel. We feel everything deeply to the core of our bones. Other people do have a choice. They guard themselves from that depth until they are sure of their feelings and that the pain that might come after is worth it.
Try taking things slow. Get to know each other. Try to tame those feelings so you dont scare him off or send him wrong signals but dont hide them.
If you ever want to talk, messege me!
