Question
I met a nice Jewish guy on a Jewish dating site and he and I very much want to get married. We love each other and both agree we are a perfect match. My parents think highly of him and his family and are hopeful we will get married. I am modern orthodox and he is not orthodox at all and has no desire to become orthodox, but he has a strong Jewish identity and some orthodox relatives he is close to. I am fine with that. I can accept him regardless of his level of observance. He is willing to move to the eruv area and let our home be kosher if we were to marry and send any kids we have to orthodox schools. The issue I am wondering about is he owns a well known non-kosher restaurant and his clientele is largely non-observant Jews. He also caters weddings and bar mitzvahs of non-orthodox Jews, some of them being intermarriages. If I were to marry him, I would benefit from the income he makes from his non-kosher business that is his livelihood. Is there a problem with me marrying him then? I don’t make enough money to sustain a household myself, and most of our income would come from his restaurant.

Question
I have been keeping the three weeks seriously every year. I also go to Israel around this time every year and it feels strange that the time of year that I should be joyous that I am "home" I am supposed to be "mourning", but I do it every year even when it feels un natural and counter intuitive. This past year I opened up an old Tanach I found that was my father's when he was a kid, there was a place holder and the page was in Yecheszkel. It mentioned Tammuz and scolding benei Yisrael at the time for mourning tammuz, a false god. Now that we are almost in Tammuz, I keep thinking about what I read. I am about to go to Israel again and I feel so strange now that I learned about this avoda zara of mourning tammuz. I learned that Sefardi customs differ with regard to the 3 weeks. Why do customs differ when it comes to Tammuz mourning practices? I am Ashkenazi, but can I follow the customs of Sefardi when it comes to mourning at this time? My husband doesn't care and thinks I should do what I feel is right. Is it an aveira to take upon ourselves a Sefardi custom?

Question
In the city of Baltimore where we live, there is a street called Cathedral Street. It is part of the fastest route to my weekly appointments at University of Maryland Medical Center according to Google Maps. But my husband says it is forbidden to drive on Cathedral Street because of its name. Instead, he takes another street called Saint Paul Street. This takes several minutes longer. He insists this is acceptable because Saint Paul was Jewish. None of this makes sense to me and he has no rabbi backing him up on this. Even the orthodox receptionist in the office where we go thinks this is all crazy.
