I hope this comes out the right way...I hope it doesn't sound harsh, but what I have to say comes from my own experience.

I have bipolar, experience some extreme states from time to time that include delusions, mild psychosis and anger. I also have borderline personality disorder and PTSD. I'm married to overall great guy.

I have a lot of problems and unresolved anger from life events. Abuse, violence, trauma etc. I also have the bipolar thing which would influence my mood/mental state even if I had not gone through a bunch of *****. I can be a walking storm of awful but I've had to learn how to control it. My husband doesn't deserve to be yelled at just because I have a chemical imbalance.

If you and your fiancee are having problems you should find some coping skills to help communicate with each other. Not just you but both of you. Finding a good therapist you can talk to on your own, and maybe have some couples sessions. There are plenty of bad therapists out there, but there are good ones. I've been through a few therapists and have felt comfortable leaving the ones that didn't understand me.

Has your husband received any treatment for combat PTSD? EMDR can be helpful, it was for me.

You can gain control of your moods without meds, but it takes a lot of hard work.

DBT might be helpful too. It can help with ways to identify moods, and regulate feelings and how we act.
