I divorced at 30, did some dating and entered a long-term relationship that I ended at 39. I tried online dating and met some decent guys, and was in a pretty serious relationship for a year. That ended 10 months ago, and I have dated since.
I second @syz‘s comment… enjoy being single and unaccountable for a while. Too many people get into the pattern of always finding the grass greener on the other side… but there are pros and cons to each situation, and it is to your benefit to make the most of the positives that you have in the here and now.
I was abused in childhood, and as a result, I had a ton of self-esteem issues that contributed to the dysfunction of my relationships… especially the earlier ones. I strongly suggest that you put a conscious effort into exploring your own inner demons and what role you played in how your marriage evolved and came undone. I am not saying that you are to blame for his cheating… but you say that he did it more than once – so consider why you stayed as long as you have. If you haven’t already, you might want to consider counseling to help minimize the risk of repeating those patterns.
Dealing with the end of a serious relationship is like dealing with a death… your entire vision of your future and your identity need to be redefined. You also need to take the time to mourn for what has been lost in terms of your hopes and dreams. You were a very different and much younger person when you entered into that relationship, so your priorities and goals in life are likely to have changed… so you need to analyze what matters most to you from 35 and on.
Get to know and love you for who you are now. Forgive yourself for the mistakes you have made in the past… and acknowledge the strength and resolve you found in yourself to stop repeating those mistakes. When we can appreciate our own value, we are more likely to attract others who will feel the same.
To establish a social life and find others with similar interests, I recommend Meetup.com. it is not a dating site! It is a site that hosts groups that anyone can organize based on any interests… book clubs, hiking groups, ski clubs, women’s groups, dining out, movies, yoga, fitness, motorcycles, dancing and basically anything you might be interested in. Like others have said, by doing what you enjoy, you are making the most of each day and having fun on your own… plus you increase your odds of making platonic friends, and perhaps finding romantic partners, with others who share common interests. Be patient!
And I will share my dating motto with you:
“High Standards, Low Expectations”
Good Luck!
