Having an understanding of why your mother-in-law might be behaving this way is only the first step to solving your problem. Next, you have to talk to your spouse. You have to tell your husband that you are feeling a bit neglected and you’d like to spend more time with him. Whatever you do, do not bad mouth or criticize your mother-in-law to your spouse. It will only cause tension and will hurt your husband. It could cause a rift between the two of you. This is his mother, after all, and he’s known her longer than he has known you. She gave him life. Never forget that. Also, be sure to still allow some alone time for mother and son. Your husband will still probably want to spend time with his mom – and that’s okay as long as he is willing to put aside some time for you, too. And you can also suggest spending time together the three of you every once in a while.
If your mother-in-law continues to come between you and your spouse, then you must be straightforward without being hurtful. Say something such as, “Honey, I respect that you need and want to spend time with your mom, but it’s really starting to cut into our alone time, and I’m worried for our relationship. What can we do to carve more time for just each other?” For extreme cases, where mother and son can not be separated and seem to have an unhealthy bond, suggest professional help in the gentlest way possible.
