When you are betrayed by your spouse it brings many different feelings. If you and he are both invested in the relationship, you would do well to seek some individual and or couple counseling.
These feelings you are experiencing are very common, and many women, in paricular, have difficulty learning to trust again. However, it sounds as if your husband is making an attempt to re establish a trusting relationship again.
The feelings you have may also stem from a feeling of inadequacy on your part. Many times women will blame themselves for their spouse's choices. If this is what you are feeling, learn to look at yourself in a more human and accepting way. These feelings can also be related to poor self esteem on your part as well.
The bot***** *****ne here is to learn to accept you and your husband's faults. Work together on building the trust and learn to rekindle the feelings you have for each other. The alternative is living in a marriage without true intimacy, the bond of trust. The fears you have will destroy the positive things about your relationship if you are not careful.
Muriel, the feelings you have are normal, but it is impotant to process these and move forward. Focus on the good things in your marriage, and on ways you can learn to trus your husband again.
I hope this helps. Gina
