so I'm just curious as to how I'm should bring this up to my boyfriend especially because money is tight, I just want to get a pair of house shoes because my shoes no longer fit, a couple pairs of sweat pants a yoga ball and maybe some evening primrose oil, he knows about me wanting the oil capsules but I don't know how to bring up the rest especially because we have Christmas for his son coming up, having to put back a lot of extra money for bills since he'll be off for a few weeks and he doesn't get paid for being off even though its his work and not him asking to be off. I just don't want it to sound like I'm asking too much, I'd be getting everything from Walmart and I need some shirts that cover my stomach too but I figure that's pushing it, but how would you guys tell your husbands/ boyfriends that you want this stuff? I'm just scared to ask because he's the only one that works and its his money and I don't want him to feel pressured or like he has to get me it.
