Communication is one of the most if not THE most important factor in a healthy relationship. This might be doomed from the start if you don't feel comfortable expressing how you feel to them. <br />
It is okay to be afraid, but you NEED to try to communicate. If your other half is not receptive to your communication then maybe its time to consider ending it.
Ask yourself if you are afraid that he will leave you if you voice your needs and wants. If so....do you have such a low opinion of HIM....or of yourself?
write down what you want to say then read it often through a day or two so that like a speech the words will be there. then sit down with your partner and start the talk with I have somethings I want to say and this is hard for me to do so please just let me say what I need to and afterwards we can talk about it but let me get it all out frist as that is the hard part for me.
Shouldn't you be completely comfortable talking to your partner? I was with a girl recently (a very intelligent one otherwise) that took not say what she wanted so far that she's lost practically any chance of achieving her dream.
your other half should love and want you becauseyou are you not try to make you into someone else. If thats not happening its time to say goodbye
practice - get someone to role play with you. the fact is you deserve to be heard. consider how it makes you feel when someone walks over you and use that to give you strength - but not to retaliate in anger
Simple. Do you want too be happy.. or live a miserable life?
