Here's the full rules:
The mission must ensure that the following requirements have been met in each individual case:
- The purpose of the trip to Germany must be plausible and comprehensible.
- The applicant must be in a position to finance his/her living and travel costs from his/her own funds or income.
- The visa holder must be prepared to leave the Schengen area before the visa expires.
- Documentary evidence must be provided of travel health insurance with a minimum coverage of 30,000 euro valid for the entire Schengen area.
Should an applicant be unable to prove that he/she can finance the journey and stay from his/her own funds, a third person may undertake to cover all costs associated with the trip in accordance with sections 66 and 68 of the Residence Act.
For 1, a written invitation from your boyfriend and proof of his residency status should be sufficient. I'll assume that 2 and 4 are straightforward as well. That leaves 3 as the main hurdle. According to this website, embassies will typically require proof of family ties and sufficient income.
The best option I can think of would be to already secure a job (i.e. employment contract) for the time after your return from Germany.
