If her dh comes home by around 1am, he retains his bodily functions, is able to engage in family life the following day, he can drive his car the following afternoon and can generally be a responsible partner and parent.
If her dh comes home later than this, he comes home, pisses all over the carpet and/or bed and vomits everywhere, stays in bed till 6pm, is verbally abusive if she tries to get him up and is unable to function as a partner or parent for the whole day.
Alternatively, her dh stays out late, doesn't make it home, ends in hospital fighting for his life either through alcohol poisoning or for being at the wrong place at the wrong time by getting punched and hitting the deck. Or down the local constabulary arrested for drunk and disorderly.
Her husband is unable to control himself. Isn't it normal someone, who loves him wants him to step up and when he doesn't, acts as op does?
To those, who say op is controlling, how else could she deal with the situation?
