While this is a concrete example, I want to know a general knowledge about this topic, so being interested in someone or being a second option.

At the end of December I matched with Girl on Tinder, she is kind of nerd type, so we had a lot of common things, comics, games, TV series, movies and many other.

Through the first two weeks of January she was really interested in me, she was writing many times and asked to meet with me during second week of January. During that time I couldn't meet with her, since I had problems with my Grandfather. So we decided to meet at third week of January (last Sunday).

For the first two weeks we had a Skype talks and she seemed even more interested in me. However, last week before the meeting, I noticed slightly less interest from her side. We were going to have a skype meeting, but she said that she went to a beautician.

Generally, she said she is considering job change and that she is having hard time with it, stomachache and bad mood.

Eventually, we met at the Sunday and the meeting was amazing, we talked almost all the time, I paid for something sweet, she bought me a dinner and at the end we kissed. I suggested we have to repeat this, she was happy to hear that.

Before our date she drived her mother to a hospital for a surgery and after our meeting her grandfather landed in a hospital also. Since, we live a bit far from each other we can't meet at any time, but I wanted invite her to me, she said it was a great idea, but she might not have a time at this week.

Today I asked about our weekend and she said that she is still doing all stuff around mother and grandfather, but she suggested a skype talk.

Now, I understand that having problems in life might confuse your mood and generally be less available, but I'm still not sure about her behaviour. Also, we seem to have less and less conversations.

If she is genuinely having "problems" in her life, I guess the best option is to stay in a contact, but do not impose myself on her too much and wait for her move if she wants to meet ?
