Join a slimming club and try and lose that weight, you'll feel so much healthier and your confidence will improve. I'm also losing weight, I was in a low place when I started and I found it daunting at first but I feel so much better for doing it and I met some awesome new friends from the group too. ❤

You will when the time is right..

Speaking as someone who did .. please don't put off dealing with your weight/health. Start small .. a few positive changes in your diet and some walking can start a habit to build from. The progress tends to reinforce itself. I've lost a fair bit and kept it off several years while still trending toward my long term goal. I wish I had started much sooner and encourage you to not make that same mistake.

I stopped dating a long time before I turned 30 and then at 34 I met someone who changed my life forever but we never ended up together like that as we both never took our chances. At 39 we met again but he’s with someone else. Go get that person if you meet them and don’t wait too long.

If you have massively gained weight and you're in your late 20s, you're going to really be massive five or ten years from now.
By then it will be almost impossible to lose it.
You should do something about that now.
Forget all this cute guys bullshit.

I don't think just thinking someone is cute is enough to be motivated to want a relationship. At least having a crush would make more sense.
