I have been dating a wonderful girl for a little over 10 months now, and for the first long while it was great. I love her and we spend a lot of time together; however, in recent months things have been more strained.
Now, about every other week or so, she has a night where if anything goes wrong she becomes very withdrawn and quiet, silently crying to herself and not talking to me about anything. It has escalated to a larger fight in the past, and I feel like I have to walk on eggshells sometimes because I hate making her feel like that. If I mention that she gets sad again, because I "Don't trust her".
For example, the last time it happened we had dinner together after I had a stressful day at work, and I was having a conversation with her while setting up a new phone that's required for my new job. We were talking while I was transferring files and she was cuddling with her housemate's puppy, but suddenly she just curled up and stopped talking. This lasted until we went to bed.
She says that these instances used to happen a lot more when she was younger, but doesn't want to see a councilor.
I am concerned about her, and want to know what I can do to help.
As a side note, this started about 3 weeks after she started hormonal birth control for the first time ever, and seems to follow the pattern after that, with her changing or forgetting her control occasionally since she began about three months ago.
