If you don’t have enough time together, your relationship is limited – or worse. Too little time together causes us to feel disconnected. Communication becomes difficult, we lose track of what the other likes and does not like, we miss changes in our spouse, and sexual desire is lost (by her if not you).
Because of how God made her, the amount of time she needs to feel connected to you is almost certainly greater than the amount of time you need to feel as connected. If you value your marriage, make time together a top priority. Make whatever changes you must, including reducing the time you spend on other things, or even eliminating some of what you do. Invest time in your marriage and it will improve – fail to invest time and your marriage will suffer.
BTW, I know I mention this regularly – there is a reason for that – it’s important!
