I have had jewelry stolen and it has gotten to a point that no matter how sweet and hard working he is I just don 't feel the same. I feel so guilty for feeling this way because you are supposed to stick by your spouse through thick and thin
Yes, in theory we are to honor our marriage vows "for better or for worse." However, we are also supposed to have boundaries as to what we will accept and not accept from our spouse. He stole your jewelry, and yet you feel guilty. You have no reason to feel guilty when an addict steals from you in order to support his habit. You don't mention if he feels any remorse or regret over stealing from you.
Naturally you don't feel the same. You're married to an addict. And addicts aren't known for respecting other people's boundaries.
The suggestion I'd make to you is to try counseling. Find someone who is experienced in addictions counseling, because he or she will understand your dilemma. I'd also suggest you pick up a copy of Codependent No More
. The first time I read it, I didn't get it because I was fixated on the addict in my life and trying to "repair" him. I finally realized that I was carrying the burden of guilt, remorse, and regret for someone who was becoming increasingly irresponsible and trampling all over me.
Time to set boundaries for yourself. Get strong enough and get the necessary tools to put your boundaries in place and enforce them. I wish you well. Being married to an addict never gets better until the addict gets serious about working a program of recovery.
