DEAR ABBY I was married to Bill for three months and I didn't know he drank until one night he came home sober. I suspected that my husband had been fooling around, and when I confronted him with the evidence he denied everything and said it would never happen again. My forty-year-old son has been paying a psychiatrist $50 an hour every week for two-and-a-half years. He must be crazy. I have a man I never could trust. Why, he cheats so much I'm not even sure this baby I'm carrying is his. I am a twenty-three-year-old liberated woman who has been on the pill for two years. It's getting expensive and I think my boyfriend should share half the cost, but I don't know him well enough to discuss money with him. A couple of women moved in across the hall from me. One is a middle-aged gym teacher and the other is a social worker in her mid-twenties. These two women go everywhere together and I've never seen a man go into their apartment or come out. Do you think they could be Lebanese? My mother is mean and short-tempered. I think she is going through her mental pause. I met this nice guy who was in the service. He's the chief petting officer. Dear ABBY: Are birth control pills deductible? KAY Dear KAY: Only if they don't work. Dear ABBY: I know boys will be boys, but my 'boy' is seventy-three and he's still chasing women. Any suggestions? ANNIE Dear ANNIE: Don't worry. My dog has been chasing cars for years, but if he ever caught one, he wouldn't know what to do with it. Dear ABBY: Do you think it would be all right if I gave my doctor a little gift? I tried for years to get pregnant and couldn't and he finally did it. Dear ABBY: Our son was married in January. Five months later his wife had a ten-pound baby girl. They said the baby was premature. Tell me, can a baby this big be that early? WONDERING Dear WONDERING: The baby was on time, the wedding was late. Forget it. Dear ABBY: Do you think about dying much? CURIOUS Dear CURIOUS: No, it's the last thing I want to do. Dear ABBY: Is it possible for a man to be in love with two women at the same time? JAKE Dear JAKE: Yes, and also hazardous. Dear ABBY: I have always wanted to have my family history traced, but I can't afford to spend a lot of money to do it. Any suggestions? SAM IN CAL. Dear SAM: Yes. Run for public office. Dear ABBY: What inspires you most to write? TED Dear TED: The Bureau of Internal Revenue. Dear ABBY: I am forty-four years old and I would like to meet a man my age with no bad habits. ROSE Dear ROSE: So would I. Dear ABBY: What's the difference between a wife and a mistress? BESS Dear BESS: Night and day.
