We rarely communicate. When we do its via text and its regarding pick up/drop off. I'm glad I dont live with her anymore. But still frustrated at the fact that she has access to texting me and now texting my mother... its just ridiculous.
If text message is the only way you can communicate, then texting it is.
She wrote me 5 times with the same text... when will our daughter be home? about 2 hrs later I responded and let her know that we had plans all afternoon and evening. She then said she would get her tomorrow.
Was there a reason that you waited two hours to respond to her text? In those two hours she sent the same text 5 times to get a response from you. In your reply, you did not answer her with a specific time- but said that you "had plans all afternoon and evening." The lack of specific time might be why she gave up on getting a concrete answer and said she would arrange pick up the next day- but this vague lack of boundary just kicks the can down the road- and you have to realize that by doing this- you'll get the same text again from her the next day- with the same question.
Why not be more specific- state a time and then abide by it? Texting a boundary is easier because it's a message rather than a conversation.
When you receive the first text- respond with a time for her, otherwise you run the risk of appearing passive aggressive- and causing her to contact your Mother out of frustration. Boundaries are needed and can be implemented by you for the benefit of all parties. She's not going to go away for good because she's the Mother of your child. She will always be in your life as long as you share custody of your child. Your Mother is also a part of the child's family and texting her should be allowed.
