<human>: Summarize the given text in a few sentences.

We are both graduate students at the same university. I am in my fourth year, and he just graduated. Since things had been going well, we planned to stay together after his graduation and make long distance work (he is going back to his home country Australia for a job that involves travel). In a year when his job allows more flexibility, we had talked about cohabiting and getting married.

The issue here is that Alex told me yesterday that he's planning to do acid with out mutual friend. I just can't wrap my mind around starting a family with someone who does hard drugs. (I'm a goody two shoes who is uncomfortable with illegal activities and illegal mind altering substances). During our relationship, he has offered me weed once, but I declined it. He has never used it while we were dating since I'm not into it. Drug use has never really even been a part of our relationship.

I should also mention that I'm fine with other people using drugs. It's your body and you can choose to do what you want with it. It just seems different to me when I think of my future husband (which is what we had talked about) doing drugs.

In every other way, I think we are extremely compatible. I've also met his parents and he's met mine and its a good fit.

Am I making a mistake by not overlooking his drug use?
