You cannot be claimed as his dependent if you did not live in his house for the entire year since you are not related.

The OP said they have lived together for seven years.

If your gross taxable income was less than $4,050 (not counting non-taxable income such as SSI or Social Security) then you can probably be a dependent.

---Tests to be a Qualifying Relative (& Unrelated Persons)---
(Must meet ALL of these tests to be a dependent)

1. The person cannot be your qualifying child or the qualifying child of any other taxpayer.

2. The person either must be related to you, or must live with you all year (all 365 days - There are exceptions for temporary absences such as school, illness, business, vacation, military service) as a member of your household.

3. The person's gross income for the year must be less than $4,050 (tax-exempt income, such as certain social security benefits, is not included in gross income)

4. You must provide more than half of the person's total support** for the year.

5. The person is not filing a joint return.

In any case, the person must be a U.S. citizen, U.S. resident alien, U.S. national, or a resident of Canada or Mexico

The above is simplified; see IRS Publication 17, for full information.

Although SSI and SSDI are not counted as income for the dependent income test (#3), that money does count as support not  provided by the taxpayer for the support test #4).
