Does it mean anything if my boyfriend likes his ex-wife’s posts?

Ok so just wondering…it’s on Strava, his ex wife posts intermittently usually hikes with friends and adds photos of herself etc and he likes her photos etc.. he didn’t for a year and then he started, does it mean anything? They split up badly and she hurt him, it’s been three years since they split and i have been with him a year after that so nearly two years now. She doesn’t like his back.
