very bad, i wouldnt tolerate it. usually it would mean she would get invited out for girls only night on weekends, going clubbing- with her single friends. meeting very hot guys that would be flirting with her, and just the second she entertains the whole situation shes unfaithful- besides alcohol is a really good excuse.
no. ill give an example of what it should be like when shes really into you:
i got together with a woman that had some issues, but she was into me and had been so for years before realizing we live in the same block
i believe it was already within the first few days we were dating she decided to start losing weight, she was a slight bit chubby- women know men dont like extra bodyfat
after about a week she felt guilty about having sex toys and decided to throw them out
it was a struggle to get her to drink alcohol or smoke cannabis which she had previously done a fair amount of- she didnt want to! she wanted to just leave her past behind entirely and focus on our thing
it fizzled out after about half a year because we had so much sexual chemistry that, it was essentially all we had, we didnt have shared interests, music, or anything- and she was also victim of modern society and all of its funny irresistable ego-boosting apps.
self control isnt a feminine personality trait i believe- alcohol just worsens this issue by a lot, and then add in her being outside of your reach, talking to other guys. its bound to go wrong. after 1 beer, 3 beers dont seem like a bad idea. and then 10 beers seem rational. asking for problems.
