For many men, the expectation levels are the most difficult to handle. Coming from a society where dating is usually a relaxed affair, Churches can seem unusually intense. Rightly or wrongly, men feel that women do not see them as just friends but as potential partners. If you are a single bloke and you go into church and talk to females they automatically think that you are on the pull. You can't make friends that easily because you are always working within the framework of the dating agency that is the church.
Relationships generally take time to mature.
It is difficult, not to say impossible, to develop a lasting relationship in an atmosphere of scrutiny. Yet that is exactly what happens, especially in churches with smaller congregations. The older the couple, the more intense this pressure is. All eyes focus on them. Indeed, that is a major contributing factor.
