This tuesday, i think, Em Sid and another guy went to spend the night at Lisa's place. While Em was ignoring Sid all the night, Lisa was enjoying the company of the guy while Grant was sleeping. They were sharing the same sheet on the couch, going to smoke together. You could see now and then the movement of Lisa's hand on the guy's body. They were looking at each other like if they knew each other for a long time.
At some point in the night, they went to the kitchen. They embrace each other for some time then the guy started to cry, Lisa also started to cry then she went to open the window to have some air. That was this week. After that, she had a huge argument with Grant, then went out with the guy. Grant seemed desperate when Lisa was absent.
This happened after Lisa came back from visiting her family last weekend. When she fucked Wilfried in february while still with Grant, she was also coming back from visiting her family.
