Divorce

I’m in the very beginning of a divorce. My husband and I have been separated for almost a month now. We haven’t filed yet, but I’m planning on filing as soon as we get an appointment with my lawyer. We have children together both under the age of 18. My husband had an affair and has always been emotionally abusive. I’m finally in a good point in my life for myself and my kids. My lawyer told me not to sleep with anyone or even go on a date because it will be considered an affair on my end as well. Once we file can I then be with who I want to be with? Or what is the time limit on that? Also I’m in Louisiana if that matters
