My question involves landlord-tenant law in the State of: Texas

Upon returning home after being gone for two and a half hours, I noticed that my kitchen light was on and that two cigarettes were missing out of my pack. My husband and I are not heavy smokers and we actually have an agreement that one will not smoke without the others presence or permission. We bought a pack of cigarettes just last night and I smoked one. When I got home, I checked the pack to see if my husband had taken any. Two were missing. I absolutely trust my husband, so when he tells me he didn't take them, I believe him. We plan on talking to our landlord tomorrow morning to find out if anyone was scheduled to do any work in our apartment but I am afraid that they will say that no one was scheduled to be here. What are my options at that point? I don't care about the cigarettes, I care that someone can come in to my apartment with no work order at any moment.
