I think if you reread your last post to me you will see the necessity of a prenup. You essentially make a strong case for its validity, when you relate through your own perspective how you do NOT want your major assets (a house – whether for monetary or sentimental reasons) jeopardized.
Hopefully will realize you should afford the same courtesy to potential suitors who would bring such up, as well as others on this board who may not want to share their future spouses “negative” assets (i.e. debt), or establish joint accounts.
Also, I was under the assumption that you currently rent and do not own a home. If this is correct, then your scenarios above make no sense. Although it is a real-estate blog, it is a personal question, and I understand if you decline to answer.
In addition, your willingness to enter into investment/2nd home deals with a future husband (who must eventually or currently own his own primary home, which you will not own, and simultaneously not share your “personal” residence, possibly commuting between the two, yet require joint accounts, is very confusing to say the least.
To be honest, your prior relationships negative outcome & your comments point to someone who maybe isn’t ready for a another relationship at this time.
