<human>: This has really been bugging me for the last seven or so months and despite trying, I've failed to fix the problem.

When I began dating my boyfriend I went on the pill. I found that suddenly whenever he does something I see as insensitive or hurtful, I start to tear up and usually end up crying. 

I don't know if it's related to the pill or not, but the pill and this being one of my most serious relationships with a guy and a lot of stress in life have all come together at once so that I can't sort out cause from cure.  I know other things don't make me cry, just things related to him.

So has anyone dealt with this? I hate breaking down in tears and being unable to have a conversation and I feel like it's going to close down lines of communication if I can't control it.  So, what can I do? My prescription is the cheapest I can get, which is what I need now, and I suspect I need the pill regardless to keep my period under control.

Can you provide a brief rundown of the text in within 3 sentences?
<bot>: I've started crying when issues in the relationship pop up and I can't seem to control it. How can I fix this?
