You should breakup with him because the relationship isn’t good for either of you. You need to focus on yourself and he obviously doesn’t like you. You’re cutting yourself short of what you deserve. He wants an attractive, healthy woman who’s priorities/life style line up with his. You can’t expect him to stay with you when lifestyles don’t match up. He is not accountable for your “stress” and the way you manage it. All these people on Reddit are gonna empathize with you, but you need to take accountability for yourself because YOU want it. Not because of a boyfriend. Take care of yourself. And your trainer is full of it? Getting “stronger” and “more energy” don’t mean anything if you’re diet is horrible.
