Relationships not lasting longer than 4-5 months

In the past 2-3 years my relationship never last longer than 3-5 months.They usually start off perfect.I get the calls ,text and attention I want. Then as things get serious 1-2 months into the relationship the calls and attention wanes. This leaves me feeling moody, uncertain and scared of being used. I usually confornt the guy to which he denies knowledge. Until he genuinly stops calling/showing interest. I usually continue to put effort into the relationship until I stop. Most times my ex's and I maintain communication which is romantic at times.I am confused as to why my relationship never seems to last while my friends are getting married. What do I keep doing wrong. I am now 27 and I am looking for a committed relationship. What am I doing wrong

You probably might need to slow down your pace in the relationship. Keep the guy anticipating for longer and give it to him slowly by slowly (both emotions and physical). The longer it takes for both of you to reach the love stage the longer it can last. All the best.

I think we would really need more info do determine what you are doing wrong, if anything. It may be the type of men you are interested in that are the problem. I would make sure to ask one of you exs why they felt the relationship failed.
