“Jennifer is extremely happy with John,” the insider tells Us. “Jen has been thankful for John’s stable love and support during issues she has faced with [ex-husband Ben Affleck’s] sobriety. He isn’t jealous and understands Jen’s commitment to helping Ben.”

The Justice League star, 46, completed a 40-day stint in rehab for alcoholism in early October after an intervention with Garner, also 46, and a sober coach. “The support I have received from my family, colleagues and fans means more to me than I can say,” he later wrote on Instagram. “It’s given me the strength and support to speak about my illness with others. Battling any addiction is a lifelong and difficult struggle. Because of that, one is never really in or out of treatment. It is a full-time commitment. I am fighting for myself and my family.”

Soon after, Affleck and the Alias alum finalized their divorce and agreed to share joint custody of their three children: Violet, 12, Seraphina, 9, and Samuel, 6
