After the War of 1812, the Federalist party died out, leaving only one political party, the Democratic Republicans. This unity and lack of separate parties caused the Era of Good Feelings, when only one political party existed.
The era of good feelings was under Monroe's Presidency after the War of 1812 which boosted the nationalism of our nascent country. However, at the same time issues of slavery rose and sectionalism intensified.
Evident political bitterness declined because the Federalists had largely dissolved and were no longer attacking the president or being attacked in return. The nation was politically united behind the Democratic-Republican Party. The Era of Good Feelings started after the War of 1812.
Men that dont show their feelings, even to the one they love have issues to be honest. They are covering something up and with good reason in their eyes. It might be embarrasing or hurtful so be careful if you want to dive into the mind of a guy...
