Is it difficult to you to express your sentiments?

I usually have no problem expressing how I feel but for some reason I have a hard time opening up with my boyfriend when I am disappointed in him. Not that this happens all the time. Actually this might be the first time that I got disappointed in him and I don't know how to open this up to him or if its a good idea to open up. What do you think?

it depends on the person i'd like to express my sentiments too. if the person is also expressive and if i feel like my feelings wont get hurt when i do express what i feel, then i will feel a bit confident in expressing my feelings. however, when it comes to people who are cold or frigid or seemingly unfeeling, it usually takes me some time before i can feel comfortable sharing my feelings with them.

Oh yes, to me it's very hard to express my sentimens, my feelings, my moods.... When I was young I was a very shy bou and also now.... I'm shy too.... time passes, but I remain the same person: a very shy person, but after knowing well a person, I become an open book: you can know all that you want from me of me, no problem, I never get ashamed speaking about myself and my sentiments.
