Hi
Venus is only 1 aspect but you also look at 5th house activities and seventh house for commitment serious partnerships,. The 5th house is the house of fun and romance. Try doing a venus return it has significance with romantic outlook and of course natal trans and progressions. A rule of 3 aspects is helpful . Also in sr chart check where the sun is and if it conjuncts descendant up to 2 degree orb I've seen that bring on serious relationships and marriage in solar return charts.
