Well I am in my third marriage and I am 33. Yes really. I've led an interesting life and now I feel very old and middle aged :) :)
My first husband was my dds dad (she is coming up to 11). I was on a path to go onto study at oxford and then met my then dh and basically my gran got cancer so I moved her in with us and cared for her till she died. Having my dd in the middle of it all. I think all the stress if it all clouded how unsuitable ex was. We were together 5 years ish. I left him when dd was 6 months old. He just didn't get the whole family thing despite us actively trying to have her.
I then returned to work and met my second husband. He was everything my ex wasn't. Really ambitious, family minded, didn't go out much etc. We were happy for 4 years, really happy. We both worked full time, very senior jobs, had lots of money, but..... I don't think there was ever that crazy in love thing. With hindsight there should have been. We grew apart, we didn't know it really. It just happened. He started going out a lot with new friends, so did I. I didn't like what he was becoming. We could never agree on how to share or spend money.
Then he left me, very cold heartedly said he didn't love me anymore. And upped and moved out in 4 weeks. Went back to his ex before me! Never heard from him again, nor has dd despite him being "dad" for most of her growing up....
I then had a second teenager type phase. My mum was living with us so she was happy to babysit and I went out a lot. Had a fuck buddy for 6 months. Loved him and got very hurt. Shagged his best friend. Gulp. Shagged someone else, totally unsuitable. All a big mess. I was drinking way too much and not sleeping. I was very depressed.
I then had a break and thought about what I really wanted. Was single for a while. Got a different less demanding job. Started online dating.
Long story short, met my now dh and he was and is everything to me..I honestly didn't believe in the one .. but well now I do. We just clicked from day one. We have the same ideals, he doesn't drink at all and I stopped too. We share everything financially and child care wise. We now have ds 15 months and I am a sahm. I financially feel happy... I never ever thought I'd feel that.
I think you don't need to panic. But you do need to thinka about what you want long term. I wasted a lot of time going for the wrong people because I had low self esteem and I didn't really know what I wanted myself let alone in someone else.
I don't think age has much to do with it. Some of my partners have been older. Dh is 8 years younger than me.
Above all, enjoy dating. Its should be fun. And if you don't get the butterflies and want to jump them every time you see them in the first 6-8 months then I'd question it. You want the sparks so when things are hard you can remember them and smile. That's the love that gets you through.
