I agree w/BlueWave...go dark. Sending messages of any sort unless it is an absolute emergency or his birthday, could be considered pursuing on his part. He knows you love him, he knows where you are...so sit back, detach and go dark. He needs to pursue you, not the other way around. When he sees you aren't sitting there waiting for him to call or text, that's when his curiosity will get the better of him and he'll contact you. When he does, be friendly, but keep the conversations short and sweet. They can't handle long winded conversations, emails or text messages.
Don't try to rush the process. You're on his time table now and it's a very, very slow one.
I also agree that if he's still in an affair, you are not on his radar. He's all about himself and the ow. Reminding him you are out there w/messages will only make him that more determined to stay away and remain dark w/you.
Pursuing is not pretty, it gives off the feeling of neediness and clinging to someone who doesn't want to be w/you at the moment. Show this man you are a strong, independent woman who can make it on her own. Just remember, the more you push, the harder he's going to pull away and run the other way.
Keep the focus on you and the changes that you are making for yourself. When the time is right he'll contact you...but if he's dark at the moment, then that means he's thinking of something else and doing other things to avoid thinking about you and the situation. Go very dim to the point of dark unless there is an emergency.
Sit quietly, the answers will reveal themselves when you least expect them to. The past is gone, the present is a gift and you need to focus on today, allow the future to reveal itself when it is ready.
