My girlfriend wants to go party from time to time. But I don't like her going to party as she told me she got to know all her Ex's at parties.

Personally, I think that if you're in a relationship, then you don't necessarily need to live in each other's pockets, it's good to have some space.

First off, why do you not like her going to these parties? Do you not trust her? Does she have a track record of doing unfaithful things? I think you need to establish why you're unsure about it, do you have securities?

It's normal for each couple to have their own set of friends and things to do.

Also, how long have you been together? After a while, her priorities may change as you advance into the relationship, potentially.

I definitely think time apart is needed and beneficial for both parties in a relationship - it's healthy to me to have your own interests and so forth outside of the coupledom. In saying that though, it sounds like perhaps the aversion to her going to parties might be rooted in trust. Do you feel like you can trust her? Has she been unfaithful to you previously?

I have to admit I wouldn't be too enthusiastic if my husband was still friends with his exes, but as long as they both understand that it's friendship only and no one is going to infringe on those boundaries then I guess I would just have to try and deal with it.

Are you bothered because you fear that she is seeing other men at parties, or you feel that she doesn't have time for you, or just because you don't want her to party at all? 1st option: depends on your level of relationship, if there's history of cheating maybe you should be worried, but if there are no signs at all then just reassure yourself that she just wants to party a bit from time to time to enjoy; solution: ask if you could come with her (if you're not with her) or make sure that she goes with her girlfriends. 2nd option: if you really don't spend time with each other, be honest and have a conversation with her, but otherwise (if you spend most of the time with each other and she just wants to party with her friends) just let her have time for herself so she doesn't feel too constricted by your relationship. 3rd option: maybe it's best to tell her that and explain calmly your reasons why you don't want her to party (without you), let her explain her side, and come to a compromise as adults.
