Take some advice from a man who has been married 20 years and still going strong. If you have to do all of this you might as well not get married at all.
Seriously. If you think even for one second that your lady is not 100% invested in whatever legacy you two are supposed to be building abandon ship.
You guys don't realize that you are supposed to be solid, know exactly what you want, and have instructions (or guidelines) for your lady to build off of. Whether women admit this or not, they want and expect this from the man they are interested in.
On the real though, a lot of guys have this issue because they are just as indecisive as a female. Their woman doesn't know what to expect because her "man" doesn't know what he wants and is unable to make solid decisions and see them through. Regardless of how long they've been together, he is afraid to commit to her, so she's looking out for herself. Instead of setting the tone early and making it clear that he intends to build a legacy with his future wife, he has a g/f that he is probably cheating on, lol. Some of you got a bm that you've impregnated and will have raising your child but not sure you want to make her your wife, lol.
Of course the woman you deal with will eventually make plans to exit. As a man you are supposed to know what you want, have plans and strategy, and also at least have a blueprint for her to build off of. Y'all don't have any instructions to give your ladies, that's why they go off trying to figure shyt out on their own. I would be a damn fool if I didn't give me wife instructions and just left her to figure everything out.
You have to set the tone from the beginning so the weaklings can make their exit. The goofy hoes will be like damn, this nikka is too serious for me. Women that want a solid man who is capable of providing leadership will fall in line.
