Khloe Kardashian is ''trying to make it work'' with Tristan Thompson.

The 'Keeping Up With The Kardashians' star got back together with her partner - with whom she shares daughter True - after he was seen kissing another woman just days before Khloe gave birth and is ''committed'' to working on the pair's relationship.

A source said: ''Right now Khloe and Tristan are trying to make it work. Khloe is committed to making things work with Tristan no matter how her family feels about it. Kourtney [Kardashian] and Kim [Kardashian] flew to Cleveland [where] they had a chat with Tristan and told him they are not going to deal with this family drama and he's either in or he's out.''

And the 34-year-old television personality's family can see that Tristan is trying and believe that is a ''positive step forward''.

The insider added to E! News: ''Since they have been back in Los Angeles, Khloe has spent a lot of time with True visiting Kim and Kanye's house and Tristan has been over a few times. The time that Tristan is there you can tell that there is tension in the room but that Khloe's family is making an effort to be civil. They're still not thrilled with Tristan [but they] can see he's trying and that's a positive step forward. They just want Khloe to be happy and this is what she wants. Khloe really wants True to have stability at home so it's important to her that they make an honest effort and that's what they're doing while in Los Angeles this summer.''
