Do you have to go through the matchmaker? What if you do online dating or go to an adult website to get laid and end up falling in love with someone who is not Jewish? Is that even an option? There has to be online dating sites for Jews, there is for Muslims. What about JDate, I'm not Jewish and have even heard of that site.
I met my first ball and chain via a hiking club, activities are a good way of meeting others, you'll already have something in common you both like. Another good way to meet potential mates (assuming they don't have to be Jewish and your not a total introvert), is through travelling, this is how I met my current partner, if you don't want to travel alone there are travel companies specifically for singles. Travelling through a developing nation is also a great way to test your ability to get along while dealing with lots of shit. I will stand by my belief that a couple who can travel together and still love each other after the trip will stay together until death do they part.
I've also found that when my friends and I have lived with partners before marriage that those marriages have lasted and are still intact - compared with the fanatics who only feel you can be together after your vows - they all happen to be divorced, I've been there and done that, not good, oh, we're married now, okay, let's move in together, nope, not a good idea, go figure. As for your friends at 25 all being married and having kids, they are not the norm, not in this day and age, you should not feel like it will not happen for you, don't put that kind of pressure on yourself. I mean, I was 30 before my first one, then 35 for my second. If I think of my 6 closet friends 4 of them are over 40 and single, only 1 of those has been married. As for kids, adopt, there are so many kids who got the shit end of the stick it ain't funny, and that's just in North America. Go over to India and see all the street kids, yes there is God awful mountains of paperwork but it's worth it.
One thing that really fucking pisses me off are people who think that you are less than them because you are not married, don't have a house, don't have kids. Ever see the movie "Happiness?" The stupid bitch who has the perfect life, well, that perfect life ain't so perfect, her husband is a child toucher, her boy jerks off all the time and at the end of the movie she kisses her dog which happens to have just licked up her boys spunk, yea, life's a fucking show and trying to be a star always puts you in the shit. You ever stop and think that maybe others put pressure on you because they want you to have the same level of misery they have? If you want to be married and have kids it will happen, just don't let it dominate your life otherwise you'll end up in a situation you don't want to be in. That happened to me at 30, a sort of, "oh fuck," if I don't do it now I will end up 80 and alone, rubbish, I rushed into something when I should have said no and it was nothing but a giant clusterfuck. Don't judge your life by what you see in others lives, they are not you and you are not them, so stop comparing, that's very hard and unfair on yourself. You're 25, you should be out there shagging everything in sight.
