My boyfriend's mum is planning a trip here(america) to see him for his graduation from graduate school.
The catch is, she does not want him to know, she wants to suprise him.
I am all for suprises and I think it is great but my boyfriend told me from the beginning if she
were to try and come without notice and I knew about it to make sure I tell him.
I am not sure what do because who I am to ruin a suprise between mum and son but at the same
time he is my boyfriend and I would rather not lie to him.

Any thoughts?!?

Don't tell him o. . . blood is thicker than water. . .and in the end, thee mother will end up despising you, and if you're thinking of going all the way with him. . . dnt tell him. . . a mother and son's bond is greater than a BF/GF bond o

so what is going to happen if she tell him?

abeg tell him! you are dating him and not the mummy

if push comes to shove( or the shit hits the fan)

you both can pretend that she ( his mum) really surprised him , let him act as if he is really surprised on the day , he sees her shikena!

Thanks for your thoughts.

@morenike09
Good idea about letting him act suprised, think i'll take your advice. He's a mummys boy so so hopefully he'll play along. Thanks again 

you better hint him.
do you not know he may have something he wants to get rid off be4 the mum comes.
it can be something as harmless as an earring or an aschtray

mamaput took it out of my mouth.hint him in a very indirect way.this way u stay on her side and have created an escape route out of blames he may later put to u. dont act like a sharpgal and tell him,his mom might spite u later(just dont take the taste out of the surprise). and be alert cos she may come earlier than she's telling u to surprise u too even though u know about d trip.

You have to be very careful on this because mums are good at spotting when their surprises are tampered with.

But if i were you, I'll tell him and I'll not tell him.
