I don't think it's fair for your boyfriend to say you "can't" go on holiday with him unless you have a job, that's your decision to make not his, especially if you have savings.
The truth is the majority of jobs these days are gotten through connections and networking, have you reached out through your network? Literally parents, family friends, neighbors, anyone who can help connect you personally to an employer. Even your boyfriend, is he helping you at all?
