I have different friends who have used different methods: Two(recently divorced 30yo woman, 35-40 divorced man) got into swing dancing (met her now husband there and they have 2 kids) and folk dancing (met his 20 year relationship gf there). Advantage of dancing is that usually people are very sociable... my folk dancing friend ended up with a huge circle of friends who would go out as a group for restaurants and other cultural events. Gym: as mentioned by others. I might recommend learning either piano or guitar, it helped me at least...
