So me 21 and my girlfriend 20 have been in a relationship for over three years now. She is my second GF and I am her first boyfriend.

At first our relationship rotated around meeting at our parent's places, watching some series and making out, you know the usual teeny stuff. Now we both live on our own in separate apartments. (We're still not sure when to move in together).

Our sex life used to be very good. I had to "teach" her how to do stuff since I am her first and only sexual partner (I myself am not that experienced), but I didn't mind and we both were happy. So the trouble began around a year ago. She turned 20 and had to change her pill to a cheaper one (we think that was the trigger) because her health insurance only covered it untill that age.

Anyway, since then she wasn't in the mood very often and she refused to talk to me about that. I tried to be patient about it. She started a very stressful college and apprenticeship mix and I thought maybe it's the reason.

We still enjoying watching shows, going to the park and the usual stuff together. She is a great woman and I enjoy her company and would love to spend my life with her.

In the last couple of months we had sex only several times and most of the time she wasn't even there mentally. She just let me do 'my thing'.  It got me really mad. I almost felt cheated on.

So that's when I tried to talk to her regarding this issue a bunch of times. She told me that she didn't feel the desire to have sex anymore and that she felt bad about it but was too afraid to tell me. We agreed that she should stop taking the pill and we should wait some time.

Things didn't change much since then and in a discussion she asked me if I still wanted to be with her. After long thinking about what I should and shouldn't say I told her that I love her company, enjoy meeting with her family more than my own. But it's true that sleeping at her side and knowing the person you love doesn't think of you in a sexual way is simply depressing.

I thought it was easy. Just wait some time, talk to her about it and we would turn a happy couple again in no time. But it isn't easy for me at all. Recently I even started to think about how easy it would be to get into an affair with someone else and afterwards return to my GF like nothing happened. I don't want this, but the temptation started to be huge. I mean we could just be best friend at this time and it wouldn't change a thing..

All of this led me to asking for a break from the relationship for some time untill we figure out what's best for us. I still love her and I believe she loves me too, but it has become too much.
I still don't know the "terms" of the break. If it shall lead to a full break up or if we should try our best to stay together.
