I think If you're partner cheats to you then you should break up with him/her. Because If he/she can do it to you. Then, he/she can do it to you again and again. Just saying.
When I was a kid I really like remote controlled cars and helicopters. One time my aunt bought me my very first remote controlled helicopter, The whole afternoon of that day I spent playing with helicopter. Together with my cousins because my aunt also bought them one.
If I have a chance to play with my toys right now that I'm already grown up. I would not be ashamed of it, because playing with toys makes you reminisce the past and makes you wonder how much you've grown. And for me that's okay.
