The challenges are numerous. Temporal mechanics play a huge role. Just the fact that time travel can create alternate timelines means that the lovers might end up in different timelines and be separated forever. There's also the issue of how society in different time periods views relationships. In some eras in the Star Trek universe, interracial or inter - species relationships are frowned upon, and a time - traveling relationship might face similar prejudices. Plus, the very act of time travel is dangerous and can put the life of the time - traveling lover at risk, which is a great obstacle for the relationship to overcome.
One challenge is the difference in cultures between different time periods. For example, if a person from the 24th century in Star Trek falls in love with someone from the 20th century, they would have different values, social norms, and technological understandings. Another challenge is the Starfleet regulations about time travel. These regulations are in place to protect the timeline, so a relationship that involves time travel might be against the rules.
