If you’re pretty sure you don’t want to spend your life with them, you might as well do both of you the favour and end the relationship now. That way you two can go find people that you know you want to spend your life with. As you said, dating as you get older does have more pressure. One reason is because as women get older many want to start their families (the almighty biological clock’s tick gets very loud around 32 years of age) and this may put off some guys. There are obviously other reasons too, such as people having different priorities in life (career, family, personal time).
