Hi all, I’m 32f. Married for two and half years. It’s an arranged marriage. What I expected from my husband is only not to have any bad habits and my husband said he don’t have any (he told me before our marriage). But he smoke cigarettes and drink alcohol and smoke substance for almost 10 years. After our marriage within a week he started smoking cigarette in front of me and I never questioned too but after few months I told him I’m not comfortable especially his substance habits at our home but he told me he was stressed becoz of financial struggle, again after few days I told the same but again he told me he just want to smoke becoz of good weather, everytime if I told that I’m not comfortable he will bring excuses. One day I cried and left home and planning to go to my mother home (it’s a different city) he never stopped, I was waited in bus stop for him that he will say he will quit substance but he never came (he thought I won’t leave) and I left the city and I stayed in my parent house for a week but my husband not willing to pick me from my parent house so I called him and he said he will quit and pick me with a condition (my parent shouldn’t ask any question about his smoking substance behaviour) so I agreed and he came and picked up me. After few days again he started his smoking habits and he never ready to quit he just normalising that. Sometime if he have that substance he will smoke more than three times a day sometimes with an empty stomach and late night which I really worried about his health. I tried to convey for rehab or counselling or therapy but he is not ready for that. He is saying substance should be legal and it’s good for health. He want to become a father too but I’m not ready for that until he quit his habit. His entire friend circle mostly of them having this habits even though they all are married. Becoz of his habit multiple times I asked for a divorce too, and he said this is the last chance that he will change but still now he didn’t changed. Is it really normal or am I overthinking ?
