Voluntary redundancy does not disqualify you from Jobseekers Benefit, unless your payment is in excess of 50,000 Euro. You should qualify for the full rate of JB (188 Euro), and your boyfriend should ask for his JA claim to be reassessed, and if you have no other income/means, he should receive 124.80
If you have been in rented accommodation for 6 months or more, and could afford the rent at the start of your tenancy you may also be eligible for rent supplement. Different counties have a maximum amount of rent that is permitted, so whether you would qualify in your current address would depends which county you are living in.
