You’re clearly feeling more confident and healthier since losing weight. It’s a shame that your partner doesn’t look after his body, but the question is why? You might simply think he’s lazy, but there’s always a reason why people don’t care enough to eat healthily or exercise.

The key to improving his attitude is trying to help him understand it. He needs to be aware of your frustration about is inaction, so try to talk to him openly about how you feel, and speak from a place of love and concern. Sometimes we want to do something on a conscious level, but our subconscious seems to be stopping us and we don’t understand why. It’s possible that he just doesn’t realise he’s fallen into bad habits, but it may be that he needs professional help to show him how to unblock whatever is stopping him from making positive changes.

Resentment is such a harmful emotion, and as you say, it’s started to affect your relationship, so if you really want things to work between you, try to let go of it for both your sakes. Perhaps, rather than thinking negatively about his appearance, give him a chance to be proactive, with love, compassion and support. Inspire him and involve him in your plans too – suggest you cook healthy meals together, or do some activities that will get you both moving.
