wife hardends heart-2

[planet]

I have been saving up for just few months since BD and did not give W my entire salary. I need to have some money for one product sourcing trip overseas for my new start-up.
She must have felt that I'm unwilling to contribute anymore. W did say she's very uncomfortable with this arrangement. I have told her the reason many times but I don't think she agrees but I do not have a choice. I'm willing to take some risk to end the rat race. This decision is not easy for me, more so after BD.
I don't know what to do. I'm not sure not being able to provide everything for my kids is the best thing right now in my situation.
Moving to my parents place and only paying W the agreed sum monthly is one option. This way I would be able to have some control over my finances. I have already transferred my share of the house to W as part of the agreement. I didn't want my kids to be burden by selling the property and moving to a new place.
But moving means I'm unable to defend my home from OM.
I'm so lost right now
