In your 20s its fine, put off getting married, but the 40 something guy who introduces you to his girlfriend sends a totally different signal than someone who introduces you to his wife (and vice versa if the genders are swapped). It says you're noncommittal, bad at relationships, maybe previously divorced, constantly shopping around, maybe breached partners trust repeatedly, whatever, take your pick. What it never says when someone is judging your book by its cover though is "this is just some guy who's been hedging against marital risk for a couple decades", any other snap judgement requires the person know you better.
The US government will help them take half your property after a breakup even without a marriage license, if they determine you were "acting married" so to speak.
