I can only add from personal experience: that's the downside to how people go about relationships these days - they can't commit until much older and only settle when it's already getting late. I honestly don't know where this came from, but it's spread to all of the Western world. People seem to think you have to shag around for decades and scrutinize every little detail of whoever you happen to be dating and almost find relief when they finally find something (most often - very minor and insignificant) to break up about and move on to the next one. Then one day they wake up and realize it's too late and they try to grab any branch of the tree they're falling from. Of course, by this time literally everyone has baggage. Personal - from all the "relationships" - just as much as family, as is your case.
I met my wife when I was... 18, I think. We married at 22. I'm 28 now. My son was born 4 months ago. We were young, no baggage and the best part - we get to face all the challenges together as we grow. Neither of us had baggage. We certainly will. But it is ours now. Could I have found a reason not to marry her? Plenty! She certainly had even more (not least the fact I spend waaay too much money on gear

). But we were wiser than that - people generally hate other people, it's in our nature. If I want, I can find so much justification for not being with someone - friends, loved one, family. But it's a dead end.
So OP - nothing much I can offer, BUT to anyone who is still young and shaging about - think about your life. Maybe the person you're currently with isn't so bad? You don't have to keep looking. Open your eyes instead. Don't be scared of making a "wrong choice" or be pressured. There's no such thing. Whoever you find, absolutely anyone - you will still have to adapt to each other very much and every single day. Marriage or any kind of serious long-term relationship is MORE about you, than it is about her.
My 2 cents
P.S. Just to be clear: we're not religiously or ethnically special to have gotten married so "early". We were your everyday college students. No high morals
P.P.S. My work gives me the opportunity to meet a lot of people of many ages. I've yet to meet someone who is sincerely happy about choosing career (and they're very successful!) over family. Everyone ends up regretting it later on. Their career then becomes their trap. You can always combine the two. We did it, despite the challenges.
