You definitely want to consider carefully what texts you provide to your lawyer. Lawyers are typically paid according to an hourly rate and if you show up with 100 texts for your lawyer to review you can be sure that they are going to charge you for the amount of time it takes them to look at those texts and decide upon their importance to your case.
It also takes a significant amount of additional time for your lawyer to prepare your court documentation when they need to continually sort through tons of text messages to find the proper evidence that they want to provide to the judge.
Try to use your judgment to determine which texts from your spouse are truly important and what you are trying to prove by showing them to your lawyer.
