I enjoy coffee, lunch, shopping, nature walks and swims alone. The occasional run. Otherwise I prefer my solitary time at home, where I can read, nap, bathe, do yoga and dance like nobody is watching because they aren't. And I prefer my time outside the house with people, I love the cinema, theatre, museums, dinner etc. but not alone. It's ok if cinema is something you like doing for dates, but you enjoy your own company otherwise. It may just have felt a bit pushed because it was. You weren't there for the love of solitude and cinema, but to prove a point to yourself/the dating world/the universe.
I was a bit like this when I stopped drinking I felt I had to prove I still enjoyed alcohol heavy environments like pubs and clubs. But those aren't my happy place anymore, I feel so much more at home walking in the woods or at a yoga class. Likewise, I haven't been dating or in a relationship for a while, and I felt a pressure initially to still enjoy eating out in the evening, dancing and dinner parties and things that I enjoyed with my ex, when actually I'm just so much happier to cook some simple homemade food at home, and use my energy for work, study and fun times with my kids. Our interests change and shift. There are places and times to avoid places eg. Romantic restaurants on Valentine's Day, that doesn't mean your unhappy being single but if you did go you probably would feel that way! And that's totally normal.
That said, if you're not happy being alone so much and being single it might be worth having some counselling or coaching to help you move towards having the relationships you do want. Being lonely is horrible and it happens at various points in our life through no fault of our own, but equally I think most people have some issues that can benefit from greater self knowledge and some outside guidance.
Are you happy in the other areas of your life like your home and work? Taking on a project or hobby can be a great way to build your confidence and self esteem and it won't feel forced if you follow your true interests.
I hope that this lull in your life passes swiftly and that you have a future filled with fabulous friends and a line of eligible bachelors await you.
