<human>: About two years ago my girlfriend moved 12 hours from her home to live with me and something that we have always talked about is exercising and losing weight, this was even before she moved that we talked about it.  I am a little overweight for my height but it's not a big deal and not as noticeable, whereas she is quite a bit overweight for her height and seems like she is a little depressed about it.  I keep talking to her about it, subtle hints such as, "You were gonna check out [insert gym name] weren't you, whatever happened with that?" but it she's still not really doing anything.  She has started going for the occasional walk for like 30-60 minutes but it's not a routine, like once a month, and hasn't done anything else.

I've started keeping track of my walks with an app and have gotten onto a plan just this month.  I'm trying to eat less, and not eat out as much but it seems like she doesn't care.  I'm the one that needs to eat better because I eat way too much and seriously need to cut back, all she needs to do is get on an exercise schedule and she would be set but she hasn't done it.

She's a little emotionally sensitive and i'm kinda good at being blunt so i'm trying to figure out what to do.  What if I just say, "Hey, I got a membership and trainer for us at X gym.  If you don't use it you're wasting me money."  That way it would motivate her to go there and exercise so i'm not wasting money and I don't really have to bring up the topic in a way that might upset her.

Could you distill the essence of the text into 1-3 sentences?
<bot>: SO said she would start exercising 2 years ago, hasn't started, complains about weight problems, trying to help her without being a jerk
