Is it normal to lose interest?
Some backstory - I'm 21 and I've been with my girlfriend over half a year. She means a lot to me. A couple of months ago she asked me to spend 2 weeks with her housesitting, which I was very enthusiastic about. However, I barely went out to socialise during this time and even after I came home for the next few weekends I found myself going out to see her each night rather than catching up with friends.
I started to feel suffocated and told her that I needed time to myself and time to see my friends. I realise that a relationship takes work but I don't want it to dominate at the expense of other friendships that I value greatly.
Right now, it's exam time, which entails a month of cramming for 12 hours a day. I need to work hard during this period and I tend to isolate myself when under this kind of stress. She's the type of person to worry a lot and I think that she feels left out and very anxious about our relationship because of the amount of time I'm spending studying.
She also doesn't really have as strong a friend group as I do, in fact she's adopted some of mine - including my best friend's girlfriend. While I welcome her having a good relationship with my friends I don't think that it's healthy to grow too close because of the divided loyalties that can arise.
This is exactly what's happening. She rang my the best-friend's-girlfriend up last night, crying about her insecurities and now my friend has been extorted into ringing me up and giving me relationship advice. I resent that he's forced to counsel me when I feel that it's none of their business.
I know she's upset and feeling isolated, but I have little choice and have given a great deal of my time to her previously at the expense of education, which is now catching up with me. I feel that she's being particularly neurotic considering that I really spoiled her for our six month anniversary and am again going with her on an overseas holiday in less than a month.
All in all I feel that it's unattractive and that I'm starting to lose interest. I really like her and it pains me that she's suffering but at the same time I think I've been clear about the fact that I need time to myself occasionally and that I have to work at this time. I don't want to end the relationship immediately. I would rather wait and see how things go with a relaxing holiday but I feel like my hand is being forced when my best friend rings me up with relationship advice.
Is the way I'm acting wrong - am I being unfair to her? Would every girl get so anxious in such a situation?
