@emilyann14,
Hello Emily
I would recommend that you go personal counselling because you need to talk about your hurt and your fears, in depth, with someone - so that you can arrive at an understanding, for yourself, why you feel this way.
Self understanding, can then lead to some more control over your emotions, or the use of tailored coping strategies, and may also improve conflict outcomes with your other half, as they arise.
That said, your partner is not a good idea for this sort of thing, because the conversation you need to have is about yourself / who you are inside / what is making you tick or hurt or fearful...it's about who you are as a person...
...but should you have that conversation with your partner, it is very likely that a number of times during such a conversation, he will hear 'you're saying I'm a bad person / this is all my fault' etc.
Nor, unless he is an exceptional or trained listener, is he likely to ask 'what when you say....what do you feel / what are your hopes / what do you think causes you to say that' etc (ie asks questions that continually clarify what you feel & why, to help your understand why you feel the way you do)
If you can see that happening, that doesn't make him a bad person - just human like all of us. Hence I'd recommend personal counselling.
