Boyfriend plans to spend 3 days with me over memorial weekend. And he has tickets to an Elvis Impersonator show. How can I tell him I can't spend that much time together. One reason I feel we get on each other nerves?

I would like to help but it's a bit difficult  since there's no detail! I don't know your whole reasoning, feelings and circumstances but i can offer you just be honest and confront the topic to your boyfriend calmly, politely and request a change of plan.

However i would also suggest to rethink your relation , cause if you feel for a simple three days you guys walking on each other's nerves then there's no purpose in your relation, means you're not handling each other pretty well and the relation doesn't sound too healthy unless well you met freshly and it's your very first days of together life! Anyway, you suppose to heal each other's nerves not to fire it up. So make sure you choose right.

Couples are supposed to be able to talk to each other about things like this .. Or you really don't have much hopes for a successful relationship.  Why do you want a boyfriend that gets on your nerves anyway?

I suspect that a number of us have friends that we like in small doses, but would not necessarily like to spend the weekend with them.

And even happily married couples get on each other's nerves occasionally.

It may just be that you prefer to have some time alone over the holiday as well as spend time with him.  There's nothing wrong with that. 

Tell him so.

A relationship in which the participants can't make reasonable accommodations for each other based on reasonable needs is not going to work out in the long run.
