Relationship Advice

t’s still going to be hard to "bring up the topic", just cause I know she has a hard time talking about this problem and I know the reason she even said anything was cause they just got done fighting where he told her that he would get a divorce if she found someone else to have sex with (I think I would’ve been mad too). She said that he had said he doesn’t feel like a man anymore and then she told me.. "Ha, he hasn’t been a real man for years".. (I presume this was sexually directed too, but who knows).. and I AM a little uncomfortable talking to her not just cause she is, but also because there are a lot of years between us. We can sit and talk about kids and stuff, but we never really talk about anything personal (until that conversation)…. so I think I will have to do it as a "joke". Or maybe have one of the guys give it to him or something. I know I’ll find a way, cause they are a sweet couple and I would hate to see them drift apart because of that. I know my parents have had fights like this as well (not so much over sex, but hurtful and accusatory fights) and it always just brings them further away from the love that they should be feeling… but then when something happens to one of them, they get all lovey dovey again and you can see they love each other… strange relationships with all that yelling going on…lol.
