my ex was like that we were together for almost 2 years and lived together part of that time. she would always go out with her friends on fri or sat or both. she was busy with school and work and blah blah during the week. i mean we lived together but still. you think your girl is a good girl cause she goes to church and hangs out with her family. my ex did the same thing and she was probably the most fvcked up girl/slvt/cokehead i have ever met so dont let that sh!t fool you. im guessing your gf is 21. so she probably wants to have fun. i would bring that sh!t up to my ex a couple times then she would turn it on me as being needy and controlling when in fact i just wanted to spend quality time once in a while. i stayed home and felt no need to go out when she was out but i shouldve gone out just as much. just act cool about it until you suspect she fvcked or whatever another dude then say somehting. like if your hanging out and her phone rings all late from some number or whatever then yea say something. i know it might be low but if you really wanna know check her cell phone logs when she goes out. fvck i started doing that when i suspected something was up and i was right. better to know than not.
