How can you show someone you really care about them and value their relationship with you?

Actually  listen to what they say, and then respond to it in the moment with compassion  and understanding, instead of inserting your parallel experiences.  Later,  remember what they have said and what they like so that you can provide them  with help or compassion that is meaningful.

expressing your true love is very important in any kind of relationship. you should always try to spend your quality time with whom you love the most. apart from this, you can also plan something special for your partner on his/her birthday or any special event to make it memorable. :)

According to me, you can only care for someone. It is up to them to see and recognize your actions. If you are too concerned about showing them, then you might end up showing off something irrelevant and insignificant. This might even deteriorate your relationship with the person. Think of it this way, recognition and appreciation from the person you are taking care is more important or the person you are taking care of??

The little things count and will most likely be noticed. Things that will show him/her that you pay attention to conversations that you remembered what they said was their favourite restaurant and always going there etc.

Everyone has peculiar taste about sex, maybe you need to find it, then satisfies him&her. Even if you totally hate that, act like you are totally into it.
