Question

get into law enforcement.

1. but according to alice, you (attend) law school nowadays.

14 - 18. right. i (get) married last month. i (not mind) being on the police force when i (be) single, but ever since i (meet) nicole, my wife, i (want) to do something less dangerous.
19 - 21. i (understand). by the way, you (have) any luck yet with those counterfeiters?

Explanation:

1. The present continuous tense "are attending" is used as the action of attending law school is ongoing now (indicated by "nowadays").
2. "Last month" indicates a past event, so the simple past tense "got" is correct.
3. The action of not minding was in the past (when single), so "didn't mind" (simple past negative).
4. "When I was single" - simple past for a past state.
5. "Ever since" + past simple ("met") - the past simple is used for the action that started the period.
6. "Ever since... have wanted" - present perfect is used to show an action that started in the past (when met Nicole) and continues to the present (wanting a less - dangerous job).
7. "I understand" - simple present for a general statement of understanding.

20 - 21. "Have you had..." - present perfect is used with "yet" to ask if an action (having luck with counterfeiters) has occurred up to now.
