Not sure if I'm being deprived or unfair?

Hey everyone, long time lurker, first time poster.

So I'm a 23-year-old male. My partner is a gorgeous 27-year-old female.

We're about two and a half years into our relationship but I would hardly describe it as smooth sailing of late.

We started off by having a lot of mind blowing sex almost every time we saw each other. I used to get head almost every time we had sex and I enjoyed returning the favour.

However about eight months ago, coinciding with a move to a new city which was preceded by a period of long distance, the sex has dried up. I have confronted her numerous times on it, but she says it's my fault because I don't put in enough effort in terms of engaging with her on a non-sexual level. She mentions wanting to go for walks and holidays (because money grows on trees) to get our spark back. Is this fair? I do other things like wine and dine her, massage her, buy flowers but still that doesn't even seem good enough to constitute a red blooded fuck.

I have tried but I feel like it just an excuse. Even after feeling like I've gone more than the extra mile I get shut down because she's too tired or not in the mood or whatever.

Am I being a complete wanker by feeling like I'm being hard done by with sex once a month? Even then she treats it like a chore. I love her but I'm getting to the end of my tether. Part of me wants everyone to say I'm the bastard, but part of me wants someone to back me up.

TL;DR: Deadbed for eight months blamed on lack of activities and holidays by partner. I feel like this is a cop out.

Any feedback is greatly appreciated.
