I think everyone deserves to have their own space even when they have someone they love. That means even LZ loves him and he loves LZ, he still should not scarify all the other things and just stay with LZ. Do you think that is fair for his kids, his sisters or the other people he also loves and loves him if he spends all his time just with the girl he loves. Love should not be that selfish. And what I feel is only when he treats others nice, he can also treat you nice in the future. The very important thing is you need to have your own space so you won’t rely on him too much. Otherwise, he will feel your love is too much burden for him. If you are really not that happy, talk to him and find a way out. Don’t quit so easily.
