Why does this happen?

So my gf has a lot of assignments this week. She said she hates who she is because she is moody snappy and not herself. I have found she is more or less affectionate and I feel stupid because of it. We have a very close relationship. Never did I say I love you oftern to a girl I never had my guard down with this girl it is different. Past few days she will tell me she loves me if she calls but if I sent a goodnight message and I say I love you as we usually do she does not write it back, now this only started happening the last few days during her assignments is it that she is just too busy and moody to feel love? I feel stupid for saying it when she doesn't back and makes me feel like I should stop then she will get insecure what the hell?

overthinking and "love" don't mix....

sounds like she's dealing with a lot of stress and you have to understand it has nothing to do with you. you're doing all the right things... keep in touch, keeping telling her you love her, but give her a little slack. if things don't get better once her work dies down, then i'd have a talk with her about what you both are looking for out of this relationship and see if her feelings have changed. she might not even realize she's acting differently! people have lots of ups and downs and appreciate someone who can support them... whether they always show it or not.
