Well, to answer those questions it would be best to gauge how your chart is interacting with recent and coming transits.
Jupiter has been in Scorpio for a few months and was together with his Mercury and Venus. Jupiter usually has an expansive influence on everything he touches, everything becomes bigger, more intense than it already is, as much any hope as any disappointment that you suffer. Mercury that rules its 7th house, is in the 12th house, which is associated with isolation, limitations, depression ... It does not mean that it is your destiny to suffer in the affective relationships and end up alone, but this can be a recurring sensation in the your life. Jupiter has been with him (it's actually still), this may have generated even more anxiety or anticipation regarding these issues, and you may have been very hurt from the latter, making you feel exhausted.
As for marriage soon, it's pretty hard to say. I think you understand that a marriage is not such an immediate process so it involves a greater maturity. However, time seems conducive to establishing serious bonds, Saturn entered Capricorn at the end of the year and will continue in it for a long time, it has a powerful effect on the planets of his birth chart. Capricorn is a cardinal and earth sign, indicating that this should be the ideal time to steady your feet, abandon illusions and start building something, work on something ... this can be taken to the level of relationships too, after all , Saturn's transit positively aspect its Venus and Mercury in Scorpio, and its Moon and Jupiter in Virgo, there may be a future opportunity to relate intimately with someone, but if it happens it would hardly be so immediate, Saturn requires time and dedication.
Uranus has been in Aries for a few years, and he is currently in his 5th house. This suggests a lot of excitement related to dating, children, creativity, pleasure and any subject that has to do with this house. The problem with Uranus is the unpredictability of what can happen, even more so in Aries, as you report, it may be that you start dating someone, but in an unexpected way, they just do not go on. Remembering that during this period, Uranus opposes its Sun in Libra, the Sun is one of the main indicators of the male figure on the chart. During this period you can simply attract inconstant men.
As for children, I think it would be convenient to observe in the natal chart its fifth house, the moon and any other planet associated with fertility and the presence of fertile signs. The fifth house has Aries on the cusp, it is not a very fruitful sign because it is a fire sign and the ruler Mars is also in a fire sign, Leo. Remembering that Mars is in square with Venus and Mercury both in Scorpio they would be an indication of fertility, since they are signs of water, considered the most fertile. The moon is in Virgo, which is reasonably fertile, together with Jupiter which together would be a strong indication to children, but he is exiled in Virgo, the Jupiterian qualities associated with abundance and growth don't work as well. All of this seems to confirm that you want children and establish a family, but you do not find the right partners or something prevents it. Regents of the fifth and seventh square each other, making everything more difficult in this area.
I think I wasn't very objective, I hope you have managed to understand my vision about it.
