I'm sorry to see this, but the fact is you still need to be looking after yourself for yours and your daughters sake, no matter whether you are or are not getting married.
Don't let this setback hinder your progress. I know there's still an issue with the Knee, but whatever you can do exercise wise, is a good thing and it's great to see you're exercising some caution on this, by not just being silly regarding activity levels.
In the long-term you and your partner are clearly very close, because you were planning to get married, so don't let this problem hinder the future of you and he and if the reason for this problem is mostly relating to him or his side of the family, (I'm not asking, it's your right to say not mine to ask), then you need to make sure he knows that this won't change what you and he have, nor should he see his connection to this derailed marriage as reason to self doubt or put strain on the relationship.
You clearly have something good together, so you both need to be strong, for your daughter, but also for the both of you, because if marriage isn't meant to be right now, that's not an indication it will never be, but if the both of you stick closely together and try your best to create a harmonius three person existance, then you will have your moment to remember very soon.
You are quitre a beautiful person on the inside and you DO have a good heart, so keep letting those things bind and keep strong what you have.
I know the world is hard and right know it seems hard because you have this and the Knee problem too and you wouldn't be blamed for thinking why am I in this situation? Why is this happening to me? I don't deserve this, which is true, but it won't solve anything, nor will it take away any hurting you might feel right now.
You both need to keep fighting for what you have and remembering what it is worth. You are intelligent not to do anything stupid, or start behaving in a way that could jeopardise most of what you have and deserve in your life.
You are a wonderful your Lady, so don't let anything right now spoil that or get in the way of the things you still need to do in your life and the things you still want to achieve, for yourself, that don't rely on you being Mrs Xyz, like losing weight, being happier, becoming an even better rolemodel to your daughter.
These things are here to test you, but if you truly believe in your life right now and every good thing in it, then your moment will come eventually to be Mrs Xyz, but right now that moment isn't here, so you need to be strong, focus on you relationship as it is, focus on your health and wellbeing and giving your daughter the Mother she needs and you CAN be okay.
We are here for you and I am here for you okay

. If it gets a little too much sometimes, message me for a one to one in confidence like before and we'll work together to get you through a few frustrating moments / days.
Keep on being human and keep on being you. I understand I really do, that life can feel like a kick in the teeth sometimes, especially when other people in life get it all their way, when some undoubtedly don't deserve it.
Life's not fair like that, but if you let your relationship suffer,
either of you, it will hurt more knowing you self inflicted damage on a good thing.
Keep your chin up, keep sticking that thumb in the air and keep smiling okay. You are such a lovely ray of sunshine when you want to be misses, so keep shining okay. I know it's a long road to being thinner and building a long-lasting, sustainable relationship / domestic unit, but for all the trying you've done and all the being there for your daughter you've done,
I'M REALLY PROUD OF YOU and I want you to have a happy life and a good life, because you DO deserve that.
So don't let anything get in the way of it all okay and don't hesitate to PM me anytime about anything. My support and understanding will be here unconditionally for you okay

.
GOOD LUCK and big, big smiles now yeah and keep making sure you don't over do it with that Knee

.
