Ben Affleck and Jennifer Garner are ''much happier'' since splitting up.

The former couple - who announced in June that they were ending their 10 year marriage - are reportedly much more content with everything since choosing to end their relationship.

A source said: ''They both seem much happier and relaxed. Jen has really been trying to put all the nanny drama to the side and she is doing well, but there is no way she would ever take Ben back.

''They are both smart when it comes to the kids and will work on putting any conflicts or differences aside.''

Meanwhile, the 'Gone Girl' star and the '13 Going On 30' actress - who have children, Violet, nine, Seraphina, six, and three-year-old Samuel, together - still ''care about each other'' and want to be a ''strong unit'' for the sake of their kids.

A source shared to PEOPLE magazine: ''They are working with a professional because there are emotions involved and they want to make this transition as easy as possible for their family.

Another insider added: ''It's not just for the kids - it's also for them. They care about each other. There is no reconciliation. They are working together and are keeping it amicable. This is something they have been working on for over a year - and they continue to be strong unit.''
