Yup, you'll be fine hombre! <- dat means man!

If you stress then you can be sure both your Mom and GF are going to stress. Lighten up. Tell each a couple of complimentary things about the other and then get out of the way. If you try and dominate the situation then you can pretty much assure it will crash and burn on impact.

Totally skip the whole "my Mother does not like" list because all that is going to do is insult your Mom and make your GF feel like she is walking on egg shells.

If your Mother invited YOU and Jenny to meet for dinner then it is nice if you take a nice hostess gift of flowers signed from both of you or perhaps high grade chocolates but I would avoid booze or drinking on the first meeting.

Assume your Mother is going to knock herself out and at least put on something respectable for her effort. Not the sappy Matchy-Match thing that shouts he is my territory now but if she is old school traditional you might want to put on a little more formal appearance for the first impression and maybe photos. My Daughter in law, that I adore by the way, wore a simple skirt and blouse, flats that flattered her but allowed her to join in the kitchen afterwards that made us fast friends.

Just this. And stop fussing.
If it is important for them to like your partner, there's nothing much you can do other than what's already suggested. Basically it's their problem if it's so important to them.
Are you seriously going to dump your GF if they don't like her? If that's the case, you best let them choose a partner for you.
I'm thinking us Dutchies are more down to earth when it comes to this stuff. Sure it's great if parents like our partners, but if they don't, tough chit. Parents should respect their children's choices and instead of trying to control them, just enjoy seeing their kids happy. Even if that includes a partner that's not to their liking.
If I'd told my either of my kids I didn't like their partner and would prefer to see them go, they would've told me to FO, lol. And quite rightfully so. It's their life, their happiness, not mine. I have no right to interfere. Mutual respect for each other's choices. Works both ways.
But yeah, that's how we do things over here.
Whatever you do, good luck.

Jimmy,

I think I see what your getting at. You think if you do "nothing" and things go south, you will feel it's your fault. Jimmy, I know this is new to you, but you've got to give your ladies more credit than that. They both know the meaning of their first meeting. You shouldn't worry. I would wait to see how the initial thing goes. Then you know if it's a wedding or a wake! Oh, Rob, you are such a stinker! Yessssss I know!

Have her bring some kind of gift ... like drinking wine or eating as you all are all together... if she cooks ... bring mom flowers or a plant if she likes that ... something small ... as a thank you ...welcoming gift... just a thought ...

its almost 4:30 am here I am not running anywhere

On my personal experience i think all girls go crazy after a while ummm why not stable

When she wants more than just sex from the relationship. Like when she wants marriage and finds out he doesn't.

Both... But long distance is much stronger.
If the couple they can be together, even thay have some problems, they still can fix together. But .. Never can work out with the long distance love.
Never can maintain it more than 1 year

Just you...And still am
