It seems like all of your friends are tied down. You get grilled on holidays why you are still single. You don't get it either. You're beautiful, nice successful etc. All you want is someone to spend Saturday nights with. If you are having trouble meeting guys here are some ideas how to meet them.
1) Expand your social circle. If all of your friends are tied down try to make new single friends. Spend time with girls who want to go out and the more you socialize the more you network and one of your friends may know someone who is perfect for you.
2) Go to new places. Don't go to the same bar every single weekend in hope to meet someone. Yes someone new could walk in but if you see the same faces and feel like you aren't getting anywhere it's time to make a change.
3) Take advantage of every opportunity that comes your way. If you get invited somewhere don't go saying but there won't be anyone there. Get out in the world. Not everyone meets love in the same place. Join a book club or go bowling on a Saturday night with your friends if you want.
4) Focus on you. Do things that will make you happy. It will take the pressure off why you are not in a relationship. When you are happy guys see it and you appear more attractive.
If you did not meet your dream guy yet and all of your friends are getting hitched don't worry. It doesn't mean that love is not out there for you it just means that you haven't met the right guy or you have to do some things different. Love is out there for everyone and sooner or later your time will come.
