Thanks for the responses. It would take an age to reply to everybody!
Somebody asked what my weight was. I don't know is the answer. I refuse to be a slave to the scales. I prefer to go by how comfortable I am in my clothes. As far as body shape goes, I'm an apple - hold all body fat around the middle, hence the back fat. I'm a size 16 on the bottom and 18 on top (I'm broad shouldered) and I'm just under 6ft tall.
There's a lot of comments about partner wanting 'us' to be more healthy. I can say with conviction this isn't about health for my partner. It is 100% about physical appearance. In the past we have clashed on our ideas of what being on a diet means. For me it's eating healthier - reducing portion sizes of some foods in favour of increasing more nutritiously dense choices. For him it's rationing and completely cutting out certain foods. As I mentioned, he has an unhealthy relationship with his own weight, which means he has an unhealthy approach to dieting.
We cook from scratch mostly and I'd say our general diet is healthy. I'm no saint, I have no self control when it comes to crisps and I bloody love them pizza!
I have made some changes, such as not buying sandwiches and crisps everyday at work. I can't eat portion sizes like I used to. I don't know if it's a side effect of age, or if my body doesn't need the fuel due to being less active in my work life. I used to love wine, but again, I just can't/don't want to drink like I used to.
I have two autoimmune issues - under-active thyroid and coeliac disease. My thyroid has not been stable since I had DD. Mixed with coeliac disease, my body doesn't absorb nutrients as well as it should. I have low iron and B12. Because of all of the above I feel exhausted most days. This is why I'm struggling to motivate myself despite knowing I would benefit from exercising more.
After reflecting on things, I see that my anger was a cover for feeling deeply hurt. My love language is definitely words of affirmation! I know deep down he would prefer me to be slimmer. I know he would find me more attractive if I was. His comment confirmed it in my mind, and I felt insecure. I know through his (other) words and actions that it doesn't mean he doesn't love me because of my weight, but yes, I would much prefer that he finds me more physically attractive. And yes, I would love to feel better about myself. I'm aware that I need to take action, but I didn't want to hear it from him disguised as 'we' need to take action.
Anyway, I told him I've been stroppy because I was hurt. We've been together for 14 years. We're not married and I've never felt the need until recently. I threw it out there a few weeks ago that we should make it official. His thought process was that he'd like us to get into shape so if we get married we'd look good in the photos. Now if he said this in the first place, I would not have been so offended. I had no idea he'd been thinking about actually getting married!
As for the back pinching thing, he said it was him being affectionate - his love language is physical touch. Maybe because I'm conscious of my back fat, I took it as more than it was... Not too sure on that one. He now knows I don't like it and I'm pretty sure he will stop doing it.
I think I've covered everything!
