If you like to cuddle, this is a good sign, as it's an easy form of non-verbal intimacy. Some people like to cuddle more than others, so it's also a good sign if you have compatibility there as well. Otherwise, they may have to seek out a Japanese cuddle cafe to fill the snuggle void in their life.
This may be the most important element to any relationship. It's crucial to be able to properly express yourself and be open and honest with your partner. This way, there aren't any unhappy surprises and you don't feel like you're constantly having to guess what they're actually thinking.
If you're looking to get married and have kids, you probably won't be able to do that if the person you're with never wants to get married or have kids. Then again, you may not want these things either, so then that would be a perfect match. Once again, communication is key to ensure you're both aware of what path the other wants to head down.
Can I be honest for a second? Butterflies in the tummy go away over time. The longer you're with someone, the harder it is to keep the flame alive. However, if you've been together for a while and still consistently find things about them that excite you, you're on the right track.
Are you an absolute goofball, but feel you need to hide your quirkier tendencies around the majority of society? If you feel like you don't need to filter yourself around your partner, then you know you've got a keeper.
Part of being able to be yourself around someone is feeling safe with them. Finding someone who gets you, and all your lovable and even not-so-lovable quirks. If you feel safe in someone's arms, never let go.
Understand that there is no such thing as a perfect relationship. There will be tough times ahead. If you can find someone willing to stick through these rough patches, they will bring you closer together and make your union much stronger.
If all of these signs are present in your current relationship, you may well be on your way to matrimony. The next big step is asking the question. Just be sure to make it something spectacular, and not something utterly embarrassing.
