Your concerns are both valid and common within a Bipolar Relationship. It can indeed by difficult to be on the receiving end of an episode driven outburst, or otherwise, but as a supporter, please try to keep in mind that your loved one is going through a lot, and although you're being hit with the shrapnel, in most cases, this is a way for our loved ones to deal with the internal noise and pain that they are dealing with.

Try to learn about your fiance's triggers and what situations may indeed fire them. Although you may not be able to avoid them, you can at least learn the patterns and prepare yourself better.

For my children, I am completely open and honest with them. My wife supports this and even works with them to help them understand as well and it can really help bind the family together even more when we discuss these things.

Giving in may be a defense mechanism, for yourself…I've been there myself and to this day, there are times where I still just give in as to move forward if I feel that the fight is not worth picking. However, this may be essentially enabling your fiance to manipulate you if you really don't agree with something and you may also be weakening your own mental foundation as well. Set boundaries and keep them in place even if it feels difficult in the beginning.

Take care and thanks again for commenting. -Rich
