Confluences I love it every time you mention that you need to show vs tell her this will be taken care of and that you realize how important a stable financial situation is to your marriage. You really "get it" on two biggies that can affect a relationship.
In one of our MC sessions awhile back the counseler made a huge deal to my H about how women really need to feel security. It tough that you just sort of have to wait it out until the funds come through to be able to offer some security but you seem pretty patient waiting for your chance to show her so keep it up.
Also it's really loving of you to foresee her being financially secure even if things don't work out. Some people get spiteful and from your posts it sounds like you'd love nothing more than for her to mutually benefit from the things you are working on. Some people try to protect their hearts and money/possessions during separation but you are leaving yourself vulnerable on both until you are sure it's over so I'm rooting for you get a second chance when your funds come through/ and you get started on this new portfolio.
