Why would a woman change after its been the same for so long /u/Frosty_Ball_7788 Sex

So I 26m and 26f girlfriend have had a very long relationship 2 years. I’ve finished inside for a long time. But up until recently about 3 to 4 months ago.. She started drastically changing. Now to the point she doesn’t want to have sex and if we do which is very rare to not finish inside her.

Yes, I’ve talked to her. She doesn’t say anything and she’s extremely difficult to get anything out of. She considers me her boyfriend.

I don’t know what to ask. The both of us used to do it a lot. Typically one time a day to maybe once a week.

I live with her. She doesn’t go anywhere asise from work. Idk.

I’m depressed
