If sending photos and news of your son was part of "looking like a great guy to get her back" then now that you're not doing that (finally, good job) try sending them as part of being a good dad. Though you and w are not together, the more your s is known and cherished by his mom the better. Filling her in on his experiences while they are apart is good. Do it in moderation. Scale back if it starts to look like you're competing with w for the best-parent prize. Be giving of those photos without being overbearing with them. Be moderate.
That communication should be about doing the best you can by s, not about managing your xw's perceptions of you.
