Will expand for longer than previous one. Lower the density, the less the expansion slows. A Critical Density Universe slows to a stop at infinite time. A Sub-critical Density Universe approaches a constant speed at infinite time. Universe steadily cools down.
Expansion continues forever.

Red dwarfs burn out as low-mass white dwarfs Remaining mass is locked into black dwarfs, cold neutron stars, and black holes. Wide binary systems are broken apart.
