Roller Coaster Break Ups

Dear Suze Q. I have a roller-coaster relationship with my ex. We separated for a year, then got together once more. We were spectacular for 3 months, better than good for 3 more after that, and now we're back to bickering even though the make-up sex is great. We're in our late 40s and I can't see another 10 years of this downhill slide. 

Dear Slider. Two critical questions. Does the good definitely outweigh the bad? Is each day better than the day before? If you can't say yes to both, then fast forward 10 years and ask if you want to be with this same, unchanged person. Major reasons for permanent break ups are irreparable breach of trust, generally incompatible, frequent fighting, or unmet emotional needs. Don't stay together for dumb reasons like you're lonely, dependent, or being pressured. This is your life and you've got another 40 years before the fun of living starts to crumble. If he's not your best fit, be brave and try on others.-SQ
