It's up to you to talk to your husband, as you've done in the past, and let him know how you feel about this woman and ask him what he's going to do based on your concerns and feelings. You can scream, shout, leave home, cry...but all that's doing is showing him that you are unable to maintain a mature and rational conversation. You are married and must face these situations with your head on straight, your emotions in check and a commitment to solving problems together. If it's not this woman, it could another woman or two trying to vie for your husband's attention or friendship. So, this is something you need to settle with him and let him know what your position is regarding his contact with other women. Whether he likes it or not, you need to express yourself. If he didn't like something you were doing or had some concerns with someone you knew, I'm sure he'd let you know immediately how he felt about it. Let your husband take care of his business; he needs to work on using subtlety with members of the opposite sex. This married woman who keeps contacting him is probably contacting other men too, single and married, cause she's in a messed-up situation and wants some attention. You communicate with her....then she'll think she has some power in your marriage, thinking she started some trouble between the two of you....it's not worth it.
