Virgo, as an Earth Sign, needs to move slowly and carefully in love matters, or they can feel unsafe. In fact, your sign may be the slowest of any other sign to trust a new partner.
Your Mercury ruler means that you need to know where you stand with others. Trying to guess their feelings only deepens your anxiety.
If you find that your partner wants to move faster than you're comfortable with, giving them a gentle reminder can help. It's a compliment that they want to be closer to you, so it does no good to take it personally, shut communication down, or even walk away. No relationship will be doubt-free - try to go with the flow more.
