Hollywood – Star couple Ben Affleck and Jennifer Garner announced their separation seven months ago, but actress isn’t ready to give up on her marriage yet. The pair, who wed in 2005, announced in June that they were divorcing. But, “Jen really thinks there is a chance they can fix their relationship,” a source told RadarOnline. Unfortunately, Affleck “wants nothing to do with getting back together,” the insider said. “Ben’s being good and not going out in public much these days, so she has this glimmer of hope they can make it work.” Sources say Garner and Affleck, despite their split, have continued to live together for the sake of their three kids: Violet, 10, Seraphina, 6, and Samuel 3. “Ben is living in the family house, but in a separate section. He has a room to himself, but it’s in an area that Jen goes to on a daily basis,” a source told E! News last month. “It has forced them to have to day-to-day interactions and spend a lot more time together than a typical separated couple. It’s working well for the kids to have both of them there in close quarters, so they have made sacrifices and agreed to do it for now.” Affleck is ostensibly wary of reconciling with Garner given that he (reportedly) already has a new flame: Sienna Miller, his “Live by Night” co-star. “Ben’s had Sienna in his sights for a while,” a source told. “They’re really flirty on set. Right now Ben just wants to keep things casual so he can concentrate on his children. He’s not looking for anything serious.”
