How can you make it easy for a man to open up when he is so timid to say how he feels? Why is he being so shy to admit his emotions when he shouldn't be afraid to tell you the truth? Are you making him afraid to speak honestly with you? Harbored emotions can make a man shy to speak up and tell how he feels about you but if you want to know what he feels inside, it is easy to calm his tension.
Make it comfortable for him to open up to you and talk honestly about the emotions he has been feeling inside. He needs a little time and room to have this conversation with you so don't rush him or put any pressure on your man to talk when he isn't quite ready to. He will in his own time tell you everything he wants to say when you make it comfortable for him to open up.
Let him know you're there, ready to listen whenever he is ready to talk to make it comfortable for him to open up. State there is no pressure or rush and you are available any time to talk. Ease his mind that you aren't worried he needs more time to discuss emotions and love.
Leave it at that. He knows now that at any time he can come to you for moral support and not have to feel vulnerable to say what he wants to tell you. Once you tell him you're there for him, leave it at that and don't keep trying to leak information from your boyfriend. Respect your man's heart and give him the time he needs. Make it comfortable for him to open up and he soon will.
